Replacement Drill Button With Reverse

How to replace a button?

To do this, you need a flat screwdriver and an ordinary pin or thin awl.

The process of replacing the button itself is carried out in the following sequence (for example, the DWT SBM-500 drill):
We unscrew the two screws holding the power cable, take it out;
We insert the awl into the hole of the wire coming from the stator, We take out the wire together with the awl.
We carry out similar manipulations to extract the second wire. If you are afraid to mix up the wires when connecting a new button, we recommend sketching a schematic diagram for connecting the drill power button;
We take a new button and connect the wires of the power cord to it in accordance with the drawn diagram. Then connect the drill itself to the button block. The wires from the stator are simply inserted into the holes until they stop;
Attach the reverse button to the block;
We install the unit in the seat in the drill body, carefully lay the wires, press the power cord with two screws;
We close the cover of the drill body, we conduct a test.

INSTRUCTIONS

Connection and repair of drill buttons

A drill is a power tool, which is found in almost every home. As a rule, inexpensive models are purchased for household purposes, which are NOT intended for intensive use.

Unlike professional power tools, they have a small resource and often fail.

One of the weakest points of a household drill is the trigger button. During operation, the contacts of the main control element often oxidize or burn out.

If at one point the drill stopped responding to pressing the trigger button or began to work every other time, do not rush to take the tool to the service center.

Replacing a button with a drill is a fairly simple procedure that even a novice master can handle. And so that there are no questions during the repair process, we have prepared a simple and understandable instruction for you.

We note in advance that any Electric Drill, regardless of the manufacturer and model, consists of the same elements, therefore the instructions below are universal.

How to replace and connect the power button to a drill. step-by-step instructions

During long-term operation under repair conditions (dust, moisture, etc.), dirt accumulates inside the start button block, which prevents the full movement of the pusher and blocks it.

Therefore, before buying a new button, you should try to clean it. This defect can be eliminated very easily. you just need to open the block and remove dirt from it with a brush. If carbon deposits have formed on the contacts, they should be cleaned with fine sandpaper. If the contact burns out, the entire unit must be replaced.

How to determine the health of a button?

To do this, you need a regular multimeter (tester) and a screwdriver.

The diagnostic process itself is carried out as follows (using the example of the common model of the DWT SBM-500 drill):

Remove the cover of the drill body by unscrewing several mounting bolts;
Unscrew the two screws on the power cord clamp;
Removing the start button block, disconnecting the reverse switch (it is usually attached to clips, which are enough to bend slightly). The reverse itself is sold separately and can also be replaced if necessary;
We take a multimeter, set the switch to the sound signal position. Closing the contacts of the tester to make sure it is working (the device should give a sound signal);
Ringing out the button. To do this, put one contact of the tester on position 2 (it should touch the wire), put the second contact on the screw, which presses the 220 volt wire. When the button is pressed all the way, the device should emit a sound signal. If this does not happen, the button does not work.

Connecting a drill button with a speed controller

Many modern models of drills, in addition to the reverse, have an electric motor speed controller built into the button. This function is very useful because it allows you to set different operating modes of the tool when performing different operations.

As for the replacement, the whole process is NOT different from the one described above. It is enough to purchase a new button for a drill with a speed controller and replace the old one in accordance with the instructions given.

By the way, on an ordinary drill, if you wish, you can always put a button with speed control. just select a block that is suitable in shape and size, as well as the corresponding power of the tool.

Mechanical breakdowns

Mechanical faults are more difficult to identify. Such breakdowns are usually accompanied by the appearance of extraneous sounds, and it will NOT work to eliminate them without disassembling the instrument. In case of poor fixation of the drill in the chuck, it will need to be replaced, since the wear of the gear connection cannot be restored on its own.

The occurrence of a wedge during operation is associated with damage to the gearbox or bearing. If you disassemble the device, then the damaged unit will be visible immediately. Worn gears or splines will indicate the need to replace them. The bearings are checked by rocking them on the shaft. If the movement is NOT smooth or extraneous sounds are heard, then the bearing is replaced. After it is possible to find the faulty unit and repair it, before assembling the device back, it is necessary to clean the gearbox from the old grease and apply a new one. Then the device will be able to serve for more than one year.

How to select replacement parts

During disassembly and maintenance of the drill, you may encounter the fact that some parts are worn out and need to be replaced. This is a common practice, however, you should not try to replace third-party components or, even worse, look for complex workarounds. A typical and gross mistake is when a conventional toggle switch is attached to the outside of the handle instead of a broken standard button. This tuning is unsafe and should be avoided.

The internal structure of the drill: 1. network cable; 2. noise suppression capacitor; 3. start button; 4. the stator of the electric motor; 5. engine bearing; 6. brush holders from the brush; 7. rotor collector; 8. drill body; 9. impeller cooling the electric motor; 10. button for switching between normal and shock modes; 11. gearbox housing; 12. reducer; 13. cartridge bearings; 14. returnable spring; 15. chuck holding the drill

All you need is to determine the manufacturer of the drill and the exact name of the model, this information is mandatory on the nameplate. The problem is that different modifications of the same model can have both compatible components and completely unsuitable ones. Focus on the appearance, and do not be lazy to clarify the main dimensions and dimensions of the part to be replaced.

With the components of the drive mechanism, everything is somewhat simpler due to the high degree of unification: the bearings are marked on the protective rings of the cage, the gears are stamped with nomenclature codes. Practice shows that you can pick up spare parts for all popular models of the tool, including representatives of the foreign series of the professional tool. In the category of exceptions, only drills over 30 years old, but even for them it is quite possible to find a donor.

How to determine the health of a button?

To do this, you need a regular multimeter (tester) and a screwdriver.

The diagnostic process itself is carried out as follows (using the example of the common model of the DWT SBM-500 drill):

Remove the cover of the drill body by unscrewing several mounting bolts;
Unscrew the two screws on the power cord clamp;
Removing the start button block, disconnecting the reverse switch (it is usually attached to clips, which are enough to bend slightly). The reverse itself is sold separately and can also be replaced if necessary;
We take a multimeter, set the switch to the sound signal position. Closing the contacts of the tester to make sure it is working (the device should give a sound signal);
Ringing out the button. To do this, put one contact of the tester on position 2 (it should touch the wire), put the second contact on the screw, which presses the 220 volt wire. When the button is pressed all the way, the device should emit a sound signal. If this does not happen, the button does not work.

Electrical faults

We begin the description of common breakdowns with the electrical and switching parts. The electrical compartment in almost every drill is located in the handle, where the button is located. To get access to it, most often you have to disassemble the drill completely. It is not difficult, but it may be difficult to snap off the case: in addition to a few screws, it is held on the latch. Having halved the case, remember the location of the elements and wiring, or better. I will take a photo, because the layout can be very intricate.

The main symptom of electrical malfunction is that the drill simply does not turn on. Try to move the power cord with the button pressed in the place where it comes out of the case: a core fracture in this place is a prerequisite for 90% of all malfunctions, if it occurs, the drill will give signs of life. You can also detect a power cut by dialing.

Another common cause of breakdown is failure of a button or reverse switch. Try to ring the contacts to which the wires are connected for the presence of commutation. The defective button can be replaced, you can try to repair it. By unscrewing a couple of small bolts that hold the body together, you will gain access to the inside. Evaluate the condition of the lamellas (they can wear off or oxidize), check the ejection mechanism, the cleanliness of the printed circuit board and the presence of burns on the main contacts.

Malfunctions of a small printed circuit board or a potentiometer inside the button, which act as a speed regulator, are NOT amenable to self-treatment. The drill in such cases either does not turn on at all, with a fully functional contact group, or works at a constant speed. The button will have to be changed.

Do not forget to also check the reliability of the crimping of the Terminals, the integrity of the insulation, the presence of oxides on the contacts. The electrical circuit of the drill is extremely simple, the main thing is to remember the order of connecting the wires.

Disassembly Electric Drill

In order to find a malfunction and repair the device, it is often necessary to disassemble the instrument. Since all devices are outwardly similar, their disassembly can be represented as follows:

Screws are unscrewed around the perimeter of the device, for this you need to use a Phillips screwdriver.
By unscrewing the screws, the halves of the case are separated.
The power button and reverse are carefully removed from the grooves.
The reducer is removed from one half. In order to take it out, you need to turn it into the seat.
Assembly takes place upside-down. With it, it is necessary to make sure that all removed elements and wires located in the recesses specially made for them.

To lubricate the mechanical parts, you will need to disassemble the gearbox. For this, the protective cover is removed, after which the screws are unscrewed and the top cover is removed. Viscous materials such as Agrinol are used as lubricants. It should be noted that repairing a power tool with your own hands if the gearbox is damaged is almost impossible, since it is difficult to purchase separately replacement of worn gears.

When repairing, you often have to face the need to disassemble the cartridge. It is a quick-release design. Fastened with threaded connection or Morse taper. In the first method, you will need to use a hex wrench to Unscrew the mount, and then, put the wrench into the chuck, tighten it tightly. The cartridge itself is unscrewed by turning the key. Removal of the mount using the Morse taper occurs by gentle blows to the end of the cartridge.

Principle of operation and main components

The drill owes its appearance to the demand for underground drilling to replace manual labor with automated. In 1870, the progenitor of the hammer drill was introduced by the American inventor Simon Ingersoll. In its work, the tool used a steam drive and storms. The advent of electric motors at the end of the 19th century made it possible to improve the instrument. So, in 1889, engineer Arthur James Arnot proposed to use an electric motor in conjunction with a drill, and already in 1895, a tool appeared that was freely held in the hands when working.

In early 1917, Arthur Arnot, working for BLACK DECKER, by connecting a button to the drill and adding a pistol grip, made the device one of the most popular power tools in the world. Since then, the design of the Electric Drill has NOT undergone any fundamental changes.

A classic drill works only in the drilling mode, but with the development of manufacturing technology, modern devices began to be equipped with an impact mode. When connected to a 220 volt network, a gear drill, converting electrical energy into mechanical energy, forces the chuck attached to the device mechanism to make a rotational movement. The number of revolutions of the chuck is controlled by a rheostat mounted in the power button, and the direction of rotation is set by reverse. The drill, clamped into the chuck, due to its shape and under the influence of high speed of rotation, easily makes a hole in hard or soft material.

To carry out a blow, the device uses reciprocating movements arising from the operation of the motor. On the axis of the chuck, a ratchet is installed, which is a toothed ring, and teeth are made on the body, creating a stop. When the hammer drill switches to hammer drilling mode, the ratchet engages and then slides off the stop. Shaft strikes vertically.

Before starting to repair the drill with your own hands, you need to determine which part of it needs to be restored.

The main parts of the drilling tool are:

Capacitor;
Engine start and stop button;
RPM control device;
Reverse switch;
Bearings;
Electric motor;
Engine cooling device;
Reducer;
Recoil spring;
Chuck;
Case elements.

Thus, the Electric Drill assemblies are divided into electrical and mechanical modules. At the same time, it should be borne in mind that the shock unit has a low performance and with frequent use of this mode in operation it quickly wears out.

Wear of the hammer unit Not only negatively affects the chiseling work, but also increases the load on the electric motor, causing it to overheat.

How to replace brushes: work in a couple of minutes

But the drill may NOT work also due to trivial malfunctions. for example, due to brushes inside the motor. This means that you cannot do without repairing brushes, while this work is quite simple. you do not even need to have special knowledge and tools. To do this, we disassemble the device, removing the brush holders from it and change the parts that are broken. By the way, there are models, the body of which cannot be disassembled. in them you just need to remove special plugs through the installation window, after which we change the brushes.

As you can see, there are various breakdowns, many of which will be subject to you, others will be feasible only for specialists in service centers. And in order to reduce the risk of such breakdowns, you need to take care of your tool, clean it after work, check the condition of parts and brushes in order to replace them with new ones in time. However, if you see that you cannot cope on your own, take the device to the workshop.

Drill button connection diagram. fix the tool yourself! How to connect the drill button yourself?

Despite the fact that this process is quite complicated, you can do all the work yourself, observing some important rules. For example, remember that opening the housing can cause all parts and loose parts to simply fall out of the housing. Naturally, this should be avoided, because then it will be quite difficult to put the device together. To do this, you can smoothly lift the cover, noting the exact location of the spare parts on paper.

The button is repaired as follows:

First, the clips for the casing are hooked, after which it is carefully pulled together;
All rusted and darkened terminals are cleaned of carbon deposits, for which you can use alcohol or sandpaper;
We reassemble the tool, Make sure that all the parts of the device are in place, and check the performance of the drill. if nothing has changed, we change the part;
We fill the turnover regulator with a compound, and then if the part fails, we simply replace it;
A frequent breakdown is the erasure of the working layer under the rheostat. it is better not to repair it, just waste your time, it is better to buy a new one and replace it.

Many are interested in where to get such a scheme? First of all, it should come with the tool when you buy it, but if there is a diagram, or you have lost it, you will have to search the Internet. After all, only with its help you will be able to carry out the repair correctly, without errors. By the way, the speed control button and the reverse control button are located in different places, and therefore they will have to be checked separately.

Checking the electric motor: causes of breakdowns and repairs

There are several reasons for drill armature or stator breakage. First of all, this is the illiterate operation of the device. For example, many users simply overload the tool, carrying out work without interruption. This leads to the fact that the drill motor does NOT have time to “rest”. The second reason lies in the bad wire harness conducts, which are often found in cheap models. That is why breakdowns of cheap tools are much more common. In this case, repairs must be carried out with the introduction of a specialized tool. And it will be better if you entrust this work to professional specialists.

However, if it was decided to carry out the repair on its own, you will certainly have a question. how to do everything right? As you already understood, an electric drill “suffers” from breakdowns of the armature and stator, and this can be checked by several signs, for example, when the tool suddenly sparks during operation. If there are “bright” signs, you can use an ohmmeter.

The stator is changed like this:

First, carefully disassemble the device case;
We remove the wires and all internal parts;
After finding out the reasons for the breakdown, we change the spare part to a new one, close the case again.

Drill button connection diagram. how to fix the problem?

Unfortunately, a tester will not be enough for you to check the performance of the tool, which is due to the fact that most of the buttons of the device are equipped with a smooth speed control, and then a regular tester may give you incorrect data. In this case, you will need a special wiring diagram for the drill button. Often in tools, one wire is connected to a terminal, and then pressing the button at the same time leads to the ringing of the Terminal. In the event that the light is on, everything is fine with the button, but if you notice a malfunction, it’s time to replace the button.

By replacing, Considering that the circuit can be either simple or with a reverse. Due to this, he carries out all the work on replacing the button only according to the scheme, does not add anything “from himself”. So, the part must be suitable in size and correspond to the power of the tool. At the same time, calculating power is a fairly simple exercise. We use the formula P = UI (taking into account that the power of the drill is 650 W), I = 2.94 A (650/220), which means that the button should be at 2.95 A.

Possible tool malfunctions. we carry out repairs ourselves

If your tool has begun to work worse, or has completely ceased to perform its direct duties, it’s time to diagnose malfunctions and try to cope with them. First, we check the wire for damage and voltage in the outlet, for which you can turn on any other device. a TV or a kettle.

If the voltage is less, you will have to replace the batteries with new ones. If the battery is working properly, the power supply is normal, look for problems in the hardware. The most common breakdowns are:

Problems with engine operation;
Wear of brushes;
Problems with button operation.

Knowing how the Electric drill button is connected, you can quickly solve the problem. In addition, a problem with the operation of the drill may arise due to the dustiness of the tool, because the drill “takes” wood, brick, and other materials. This means that you should take care to clean the device after each use. this is the only way to reduce the risk of malfunction due to dirty tools. That is why after you have carried out repairs in the apartment, immediately clean the drill.

Required tools and materials

You can also repair a drill on your own, the main thing is to know the causes of breakdowns and methods of their “treatment”. Today we will talk about how the drill button connection diagram looks like, and we will not ignore other malfunctions, thanks to which you will be the happy owner of a working tool.

How to detach an old button?

To detach it, you need a thin slotted (straight) screwdriver and a pin. Use a screwdriver to unscrew the existing bolts that clamp the cables coming from the power plug.

The rest of the wires are secured with a spring clip. To disconnect them, you need to thread sharp pins into the recess where the terminal is located. Thanks to this action, the terminal is released and the wire is removed along with the pin.

Drill button connection diagram for replacing it

If for some reason the drill stops working, you need to figure out what the reason is. The first step is to check if there is voltage in the extension cord and the outlet. This can be done with a single-pole indicator, it will only show the phase, but if a break occurs on the neutral wire, then it will be useless. The easiest way is to plug another electrical appliance into the same extension cord and the same outlet and thereby check their working condition.

Note! All electrical devices must be checked according to the scheme.

It is best to check the drill button with an ohmmeter or a tester according to its scheme. Connect the device to the contacts on the plug, the device will NOT react, because the start button is NOT in the working position. After pressing it, the device will show or beep to notify that the whole circuit is damaged. If the reason is in the button, then consider the device of the drill button and its repair.

A tester is not always enough to test a button. This is due to the fact that most of the buttons have a smooth adjustment of the rotation speed, so a simple tester does NOT check them correctly. For correct verification, you will have to use a special scheme. Often, in a drill, one wire is connected to one terminal. Therefore, with the simultaneous pressing of the button, all Terminals are dialed. If at the same time the light comes on, then everything is in order with the button, if there is, then the easiest way to eliminate the malfunction is to replace it.

Important! In order for the engine to work with reverse, it is necessary to reverse the connection of the wires to the brushes.

When making a replacement, it must be borne in mind that the circuit can be ordinary and with a reverse. In this regard, the replacement of the drill button should be carried out purely according to the scheme. Necessary Please note that it must be the right size, which goes without saying, and also match the power of the drill. It is quite simple to calculate the required power: for example, the power of the tool is 650 W, we use the formula P = UI and we get I = 650/220 = 2.94 A. So, we need a 2.95 A button for our drill.

Repairing a drill button is a rather complicated process, it requires certain skills. It must be understood that when you open the case, many parts will simply fall out of it. To avoid this, gently lift the lid and mark the location of all parts. The button is disassembled and repaired in the following order:

The clamps of the protective casing are hooked, and it is pulled together;
All blackened terminals are cleaned of carbon deposits with the help of alcohol or fine-grain sandpaper;
Then everything is assembled again, and if the work is NOT restored, then a replacement occurs;
The speed regulator is completely filled with compound, therefore, if it fails, it only needs to be changed;
Another frequent breakdown is erasing the working layer under the rheostat slider. It makes no sense to repair it, so it is easier to replace the entire button.

In order to know how to connect the drill button, you need to work according to the scheme that should be available in the tool. If there is none, then you need to find it on the Internet. Only with its help it is possible to carry out repairs and connections quickly and correctly. Advice! The speed controller and reverse control are located in different housings, therefore they must be checked separately.

Wiring diagram for the switch of a shovel drill

Quite often, the electric drill stops working due to a breakdown of its switch with speed control (it does not turn on, but the speed is not regulated), we disassemble the drill, we try to do something, and when we understand that it is a switch with speed control, there are many wires from him already cut off and which one was unknown where. To solve this problem, you will need information: how to replace a switch with an adjustment in a drill In order for the engine to start working in the opposite direction, you need to swap the connection of the wires to the brush (in the button with a reverse, this is done using the switch lever). I want to draw your attention when buying a switch, it must correspond not only to the size, but also to the power of your drill. Let’s calculate: we have a 650W drill, P = UI, I = 650/220 = 2.95, it turns out we need a switch at U =

220V, I = NOT less than 2.95, so the Bue-3 switch is suitable for us

It is also advisable when replacing the speed control switch, supply new capacitors (capacity).

Drill Button Connection Diagrams

Electric drill repairs can be done on your own. This requires knowing certain types of breakdowns and methods for restoring units. The connection diagram of the Electric drill button requires special attention. You should also consider the malfunctions associated with its operation. If you know the intricacies of your instrument, it will be easy to fix it at any time. Before repairing, you should find out which wiring diagram for the drill button is used in a particular model.

Button connection

Despite the complexity of the process of replacing a button, you can do it yourself. It is important to follow certain rules. For example, it must be remembered that inaccurate opening of the case often entails the loss of some parts. If this is not avoided, the assembly of the device will be quite difficult.

To open the drill, it is necessary to very smoothly lift the lid, and then mark the locations of the various elements of the device on paper. Button repair is carried out as follows:

First you need to pick up the casing latches and pull them off.
Any terminal that has carbon deposits or rust on must be cleaned. For this purpose, use sandpaper or alcohol.
After that, it is necessary to reassemble the tool so that all elements of the device remain in place. Then you need to check the performance of the drill.
Often, abrasion of the working surface under the rheostat becomes a prerequisite for breakage. It’s better NOT to do it. it’s easier to buy a new one. Such a detail is highly complex.

Many owners of electric drills with reverse are interested in where to find such a scheme. First of all, you should look for it in the instructions for the tool. However, if such data is available, you will have to ask a professional for advice or download the manual on the Internet. Instructions for many drills are on the manufacturer’s website.

Connection diagram

It is not enough to use only a tester to check the functionality of a tool. The main part of the device buttons is equipped with a smooth speed control mechanism. That is why the tester can give incorrect values. In this case, familiarize yourself with the specific connection diagram of the button.

Often in electric drills only 1 wire goes to the terminals. Due to this, when the contact is closed with a button, the terminals are dialed. In this case, the flashing light means that everything is in order with the button. In the case of a faulty mechanism, the tester will not respond.

When replacing a button, it should be borne in mind that the circuit can have a rather simple device, or it can be performed with a reverse. Therefore, each process associated with the replacement of the tool button must be performed in accordance with the scheme. Nothing can be added. For example, the size of the new part must be suitable. Reverse drills will take a little longer to check for faults than simple models.

Possible malfunctions

If the drill’s performance has begun to deteriorate, it is worth diagnosing it. The drive must first be checked for various damages. Also, first of all, the presence of voltage in the network from which the device is powered is checked.

Battery models can be diagnosed using a special device. a tester. The voltage indicated by the manufacturer must correspond to the value given by the testing device.

If the voltage is lower, replace the battery. The most common drill malfunctions:

Problems arising from a malfunction of the button mechanism;
Engine breakdown;
Wear of brushes.

Knowing how the tool button is connected can easily deal with the breakage associated with this part. It should also be remembered that many of the problems that arise when working with a drill are associated with the dustiness of the device. It should be cleaned after each use. Otherwise, the tool will last much less.

Checking the electric motor

Breakage of the stator or drill armature can happen for various reasons. Most likely, this was caused by non-observance of the rules for operating the device. For example, in many cases, the tool is simply overloaded, working without interruption. In this case, the engine wears out much faster.

The second reason is usually the low quality of the winding wire, which is often used in budget products. Cheap drills break much more often than more expensive ones. In this case, repairs are carried out using Special tools.

As you can see, repairing a drill with an accurate diagram of the device can be done by hand. This job will NOT take long if done carefully.
