Driving the drill button connection to replace it

Common causes of failure

If for some reason the drill ceases to function, it is necessary to understand the reason.The first step is to check whether there is tension in the extender and a power outlet.This can be a single-pole display, it will show only a phase, but if there was a break in the neutral conductor, it will be useless.The easiest way - is to include another electrical device into the same power strip and the same socket and thereby check their operating status.

Note!Check all the electrical appliances should be carried out under the scheme.

Check drill button is best to use an ohmmeter or tester for her scheme.Connecting the device to the contacts on the plug, the device is not responding, because the start button is not in the working position.Once it hit, the device will beep or alert about the whole scheme or damaged.If the cause of the button, the device will consider drilling buttons and its repair.

Wiring drill buttons and check its efficiency

To check the buttons are not always sufficiently tester.This is due to the fact that most of the buttons have a smooth adjustment of the rotational speed, so a simple tester makes them a check is not correct.For proper verification will have to use a special scheme.Often drill one wire attached to one terminal.Therefore, while pressing the button is continuity of all terminals.If the lamp lights, the button is OK, but if not, then the easiest way to solve the problem - it is to replace it.

Important!To work with the engine thrust reverser, you must swap the switch wires to the brushes.

Making the change, you must take into account that the scheme is common and reversible.In connection with these replacement drill buttons must be carried out strictly according to the scheme.Attention is drawn to the fact that it must be suitable in size, that goes without saying, as well as comply with a power drill.Calculate the power required is quite simple: for example, the tool capacity of 650 watts, use the formula P = U * I get and I = 650/220 = 2.94 A. This means that we need a button to 2.95 A for our drills.

Repair switch Repair

drill buttons - a complex process, it requires certain skills.It should be understood that the housing opening many details simply fall out of it.To avoid this, gently lift the lid and mark the location of all the details.Disassembled and repaired the button in the following order:

• picks locks guard, and it contracts;
• blackened All terminals with alcohol or nazhdachki fine grain cleaned of soot;
• Then everything going again, and if the operation is not restored, it is replaced;
• Governor completely filled compound, so if it fails, it is only necessary to change;
• Another common failure - is erasing the working layer below the slider rheostat.Repairing it does not make sense, so it's easier to replace the button completely.

In order to know how to connect the drill button, you need to work on the scheme, which should be available in the tool.If there is none, then you need to find it on the Internet.Only it can help to repair and connect quickly and correctly. Tip! Speed ​​control and reverse control are located in different buildings, because of their need to verify separately.
