How to fix the light switch - fix the switch

In the case when one of the room switches has ceased to function, there is absolutely no need to immediately call an electrician for help, as it is usually possible to repair the light switch on your own. Breakdown of this kind often occurs only because of poor contact in the automatic switch assembly, the plates of which over time become covered with soot arising from constant sparking. To resume the operation of this node, you just need to clean the contact parts of the switch, after which the device will last for a long time.

Preliminary procedures

A power outage

First of all, it is important to remember that before repairing the light switch, any other electrical equipment or some part of the wiring, it is necessary to turn off the power supply at the place of work. The repair of the breakdown should be started only after the automatic circuit breaker is disconnected, directly through which electricity is supplied to the premises.

In order to repair a broken switch, you will need the following tools and devices:

• a multimeter or a conventional indicator of the "screwdriver" type;
• a small skin;
• marker;
• standard screwdriver of the required volume.

How to disassemble and clean the contacts

Disassemble and clean the contacts

When the switch does not always work, the breakage factor is rather contained in the burnt contacts of the switching system. The stages of repair in this case look like this:

1. After the power supply is turned off, it is necessary to check once again that there is no electricity, for this purpose an indicator screwdriver or multimeter is installed in the socket.
2. Then it is necessary to pick up the edge of the switch button with a thin narrow screwdriver and dismantle it from the case; the double switch is removed in a similar way. When removing the buttons, there is no need to make efforts, as they are more often removed without difficulty.
3. The next stage also picks up the edge of the plastic frame of the switch body and removes it.
4. Next, use the indicator screwdriver again, once again making sure that there is no voltage at the terminals of the device to be disassembled.
5. In the case where the switch is a two-button switch, it is necessary to mark with a marker a wire that supplies electricity and is common to the two switching modes.
6. In the next step, using a screwdriver, loosen the tightening of 2 screws located at the edges of the switch body, after which they should be removed from the plastic socket.
7. In the future, insulating tape is wrapped with bare supply wires and a previously disconnected circuit breaker is connected, if necessary, for example, to confirm the fact that the breakdown is contained in a switch.

In the process of disassembling the internal system of the device, it is very important to place all the parts removed from it in order on the table; disassembly.

Insulation of wires

Contacts to be cleaned are on a plastic base that looks like hemisphere, they are located under the switch button. They can certainly be found on the distinctive features of soot of dark colors, which appears as a result of sparking and, as a rule, they are also the main cause of damage.

In order to clean the contacts from the burning and dirt, you can use a small fine-grained skin.

Installation of the switch

Connection of the two-button switch

After the light switch is repaired , you need to install it in its place, you need to perform all the same, but in reverse order. In the event of difficulties, you can use photos, if any, that were made when dismantling the device.

From the very beginning, the wire marked with a marker and then all the remaining wires are connected to one of the terminals. Then they fix the device in the underside and place the frame of the case and the decorating cover in place.

It often happens that the cover cannot be fixed to the base of the device. In this situation, it is necessary to unscrew the bolts that hold the switch body in the socket for a couple of turns, and after fixing all the elements, re-tighten them. In the case of the correct location of the housing switch cover must approach it in the absence of any effort.

Only after completing all the repair work on the circuit breaker, is it allowed to turn on the circuit breaker and test the operation of the circuit breaker.In this embodiment, it is advised to check the device a number of times, this will make sure that the arcing is gone and that the switch will work properly.

Reduce the possibility of contact burning is obtained if the lighting devices and light bulbs are installed in the room.
