So, in the starting position, you have a master switch that is securely mounted inside the strobe lights. To get started, prepare a tool in order to quickly disassemble the case – a screwdriver, it will be enough.

Instructions for disassembling the light switch in the apartment are as follows:

1. Disconnect the circuit breaker that protects the wires from network congestion and short-circuiting.
2. Make sure there is no electricity in the room using a screwdriver.
3. Remove the key( s ). No matter which key type  you use: single key, double key or with three keys. To remove the key, you need to press it with your fingers on the sides (in the middle) and carefully remove it from the body (as shown in the photo). Sometimes the part “sits” tightly inside the case and in order to get it out, it is necessary to pry one of the edges with a screwdriver.
4. Remove the decorative frame. In some cases, the frame is fixed with screws from the inside, more often the part is fixed by grooves, where you need to apply a little pressure on the screwdriver to dismantle the electrical accessories. Another option for fixing the frame is with the help of an additional element installed in the grooves of the caliper.
5. Remove the “core” from the socket. On the sides of the case there are two screws that secure the mechanism to the wall. All you have to do is unscrew it with a screwdriver. There is another option to hold the body in the socket – blowing off the legs. It must be dismantled by unscrewing the screws on the sides that adjust the thrust angle.
6. Disconnect the lead wires. Phase, ground and zero can be fixed by self-closing terminals or screw clamp. In the first case, you just need to click on the locking levers and pull the cores out of the connectors. The screw clamps must be loosened with a screwdriver and the wires carefully removed.

These are the entire disassembly instructions for the light switch. As you can see, there is nothing complicated in such an event.

As for the repair (for which it was necessary to disassemble the light switch), it all comes down to the following actions:

• If traces of melting of the mechanism are visible inside the case (the plastic has turned yellow, some areas are charred), you can without hesitation throw away the product and go to the store to buy a new one. Today, the cost of a master switch is not very high, but safety is more important!
• If there is no visible damage, try reinserting the cores and tightening them carefully. Perhaps the connection has simply weakened, as a result of which the switch has stopped working. If it does not help, then the reason is most likely in the wiring, try ringing it with a multimeter, on which basis draw conclusions.

After finding the cause of the failure, and most likely it is a poor connection, the assembly is done in the reverse order. We hope you now understand how to disassemble a light switch with your own hands!
