How to connect the live wire and the zero wire of the double-control switch?

L 1 and L2 are neither neutral nor live. L stands for fire line; N stands for zero line;

L 1 or L2, a terminal of the lamp (or controlled equipment). When the switch is turned on, l and L 1 are turned on. At the same time, the L and L2 terminals are disconnected. When the switch is pressed, L and L2 are turned on. At the same time, l and L 1 terminals are disconnected.

L 1 and L2 only appear in double-control switches or multi-control switches, so introduce the connection of double-control switches:

1, and the terminals of double-control switches are generally marked with "l", "L 1" and "L2". When the L terminal enters the line, one end of L 1 and L2 is connected to L, and after the switch is pressed, the other end of L 1 and L2 is connected to L. ..

2. Expose the copper wire of the wire.

3. The L of the left switch is used as the live wire input, and the L 1 and L2 of the two switches are correspondingly connected, and then the L of the right switch is connected to one end of the lighting lamp, and the other end of the lighting lamp is connected to the zero line.

4, bare copper wire wrapped with insulating tape, in case of leakage.

5. Connect the plug between the live wire and the neutral wire to complete the wiring of the whole double-control switch.

6. The diagram below is a hand-drawn circuit diagram for reference only.

Note: 1. When connecting electricity, be sure to cut off the power supply in advance to prevent electric shock.

2. Be sure to stick the bare copper wire with insulating tape to prevent electric shock or short circuit.
