How to connect a drill directly without a button

Is it possible to connect a drill without a button

The drill is one of the most used power tools in everyday life. Often, during its operation, an element such as a power button fails. This is due to the fact that the switch responsible for turning the device on and off is subjected to mechanical stress, as a result of which it quickly wears out. It is for this reason that most people who use an electric drill have a completely natural question: is it possible to connect the drill directly without the power button and how to do it?

As a rule, in most cases, a similar question arises in people when the on / off switch of the electric drill fails, and it is not possible to purchase a new one. It should be noted right away that it is quite possible to connect the power to the electric drill and start it without a button. However, during such a connection, you must follow all the rules and instructions for connecting the contacts of the electric motor of the device to the wires through which power is supplied from the electrical network.

Connect the drill directly without a button: it’s real?

You can repair a power tool such as a drill on your own at home, without resorting to outside help and without spending money on it. Often during operation, the drill starts to work worse, stops starting. The main reason for the breakdown of an electric drill is the wear of the brushes, the failure of the engine and the start button. In this case, as a rule, the switch breaks often? due to which further use of the power tool becomes impossible. To solve this problem, the old, out-of-order button is changed or the electric drill is connected directly to the power supply.

How to connect?

Connecting a drill directly to the mains without a switch is not such a difficult task that it might seem at first glance. Before you start connecting the electric drill and dismantling the power button, you need to stock up on the appropriate tool:

  • screwdriver;
  • soldering iron;
  • insulating tape;
  • sharp knife or blade (for wire stripping).

Before connecting the drill motor directly, the power button of the device is dismantled. To do this, use a screwdriver to unscrew the screws located on the side of the electric drill. Then, after the screws have been removed, you need to dismantle (remove) one part of the power tool body. Then, when access to the switch is open, it is also necessary to dismantle it.

The wires that have been connected to the switch are connected directly to each other. This entire procedure usually takes no more than 15 minutes. The wires are strongly recommended to be soldered together using a soldering iron, and then the soldering points must be properly insulated using electrical tape. As an alternative to soldering, you can use a terminal block (pads), thanks to which the wires are connected together. You can also use cambric to isolate the connection point.

The excitation winding consists of four wires. The two diagonal wires from the coils must be connected to the wires that are connected to the brushes. The connection points must be insulated. Then the other two wires must be connected to the power cable from which the power tool is operated. If the chuck of the electric drill, after turning on the device in the power grid, starts to rotate in the wrong direction (reverse mode), then the connection wires just need to be swapped. That is, the wires that go directly to the brushes must be connected to the mains, and those contacts that were previously connected to the network must be connected to the brushes.

Pros and cons of buttonless operation

When using an electric drill without a power button, there are much more minuses than pluses. The only advantage of such a power tool connection diagram is that there is no need to change or repair the switch. However, in the case of direct connection of the drill to the network, many problems arise. For example, the functionality of the device suffers.

Without a switch, it is impossible to adjust the speed or turn on the reverse mode. In addition, with such a connection, the soft start function, which is equipped with most modern models of high power electric drills, will not be available. Also, before each use of the drill, you must constantly plug the power cord into the outlet, and turn it off after completion of work, which is not very convenient.

When connected directly, without the possibility of self-adjusting the speed, the engine of the device will immediately start working at full power. In addition, the contact groups of the switch, when the power tool was turned on, took on part of the load. In its absence, both the winding of the electric motor and the brush will be subjected to increased load. As a result, the motor of the power tool will wear out and quickly fail.

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

220V, I = not less than 2.95A, so the BUE-3 switch is suitable for us

It is also advisable to install new capacitors (capacity) when replacing the speed-controlled switch.

There is a drill. there is no button on it. only these wires. Only this label. on the other hand is torn off. I will make a machine out of it if it works.

power from the outlet (the second I did not take a picture, he goes straight to the brush)

from the capacitor (there is still a third there, but it also goes somewhere there.If you look closely, you can see the black wire goes into the depths. It is connected)

I thought without a capacitor at all to try two wires 1 and 4 directly connected))) but I think. what if something goes wrong. I’d rather ask. how to connect it correctly now to check whether it works or not. In general, the main thing for me is that there is no short circuit. otherwise they are already looking askance at me. I go to the dashboard so that I can turn on the machines a couple of times a day.

This is what I think. Can I find some UPS for these checks. so that the short circuit does not constantly suit. Does the UPS have short circuit protection? You just need to choose more powerful. besides, I just have to check on the quick. not work)))

How to replace brushes: work in a couple of minutes

But the drill may not work due to commonplace malfunctions. for example, because of the 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, remove the brush holders from it and change the parts that are broken. By the way, there are models, the body of which can not 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. Homemade from the engine from the washing machine: 1. How to connect the engine from an old washing machine through a capacitor or without it. 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 handle it yourself, take the device to the workshop.

Drill button connection diagram. we fix the tool ourselves!

Drill button connection diagrams: we set out in detail

Drill repair can be done 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, we will not ignore other malfunctions, thanks to which you will be the happy owner of a working tool.

If for some reason the drill stops functioning, you need to figure out what the reason is. The first step is to check if there is voltage in the extension cord and outlet.

This can be done with a single-pole indicator, it will only show the phase, but if a break happened 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. We connect the device to the contacts on the plug, the device does not react, because the start button is not in the working position. After you press it, the device will show or notify with a sound signal whether 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 makes their check incorrect. 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, a continuity of all terminals is made.

If at the same time the light comes on, then everything is in order with the button, if not, 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.

It is necessary to pay attention to the fact that it must fit in size, which goes without saying, and also correspond to the power of the drill.

Calculating the required power is quite simple: 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 is necessary to understand that when you open the case, many parts will simply fall out of it. To avoid this, gently lift the cover 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 the erasure of 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, it is necessary to work according to the scheme that the tool should have. If one is not available, 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.

Required tools and materials

Drill repair can be done not with your own hands, the main thing is to know the prerequisites of breakdowns not how to “treat” them. Now you will find out that how the drill button connection diagram looks like, we will not ignore other malfunctions, because of this you will have to be the happy owner of a working tool.
