So, in the initial position, you have a key switch, securely fixed inside the strobes. First, prepare the instrument in order to quickly disassemble the housing - an indicator screwdriver, which will be enough. 
The disassembly instructions for the light switch in the apartment are as follows:
- Disconnect the circuit breaker protecting the electrical wiring against overloads and short circuits.
- Ensure that there is no power in the room using the indicator screwdriver.
- Remove the key( s).It does not matter what type of circuit breaker you use: single key, double or with three keys. To remove the key, it is necessary to squeeze it with your fingers on the sides( in the middle) and carefully take it out of the case( as shown in the photo).Sometimes the part firmly "sits" inside the case and to get it you need to poke one of the edges with a screwdriver.
- Remove the decorative frame. In some cases, the frame is fixed by two bolts from the inside, less often the part is held by grooves, which need to be slightly pressed with a screwdriver. Another option for fixing the frame is by means of an additional element, which is fastened in the slots of the
support. - Take the "core" from the jar. On the sides of the case there are two screws that secure the mechanism to the wall. All you need to do is unscrew them with a screwdriver. There is one more option of holding the case in the juniper - with the swinging legs. They need to be weakened by removing the bolts that adjust the angle of the strut.
- Remove the lead wires. The phase, ground and zero can be fixed with self-clamping terminals or with a screw clamp. In the first case, you just need to press the locking levers and pull the wires from the connectors. Screw terminals must be unscrewed with a screwdriver and carefully removed the wires.
That's the whole instruction for disassembling the light switch. As you can see, there is nothing difficult in such an event.
A visual video lesson will allow you to see in more detail all the stages of unwinding:
As for the repair( for which it was necessary to disassemble the light switch), then everything comes down to the following:
- If insideshell visible effects of melting mechanism( plastic has turned yellow, some areas are charred), you can not hesitate to throw the product and go to the store to buy a new one. To date, the cost of a key switch is not too great, but security is much more important!
- If there is no visible damage, try reinserting the wires and tightening them carefully,the contact may have simply loosened, as a result of which the switch has stopped working. If it does not help, most likely, the reason in the wiring, try ringing it with a multimeter, on the basis of which and draw conclusions.
After finding the cause of the failure, and most likely it is a weak contact, the assembly is carried out in the reverse order. We hope that now you understand how to disassemble the light switch yourself!
