1, remove the switch, this is very important, and warn people around you, especially children, that the circuit is being repaired and it is forbidden to start the switch.

2. Find the broken line and determine which line is connected to which line.

3. Leak a part of the threaded ends of the connecting wires to ensure that they can be screwed together. You can burn it with a lighter, peel it with a diagonal pliers, and sometimes cut it with scissors, depending on the type and material of the inner envelope.

4, thread leakage, thread together.

5. Move the switch to confirm whether it is connected, connected and powered on. Then hit the brakes again.

6. After confirming OK, wrap the joint and the left and right redundant parts with insulating electrical tape, and then wrap them twice. Note that the winding length must be wider than the joint, and there can be no floor winding to prevent contact with other threads or water leakage.

7. If the two connectors are staggered as far as possible, short circuit or danger will be prevented after the adhesive tape falls off.

After the wire is wound, turn the switch to the normal power supply.
