We all know that household electricity usually has three lines of fire wire, zero wire and ground wire. The ground wire usually uses yellow-green two-color wire. When wiring the switch socket, we must first use the test pencil to find the fire and the zero wire. By using color as a good mark.

a. If the wall switch is used to control the on/off of the power supply of the socket, the wiring method is as follows: firstly connect the L terminal of the line to the switch, (ie, the incoming line of the live line), and then connect the L1 terminal of the switch (ie the live line) The outlet port is connected to the L terminal of the two-hole socket (ie, the live wire terminal), and then the neutral wire is connected to the N terminal (zero wire terminal) of the socket.

b. If the inner socket does not need to be controlled by the switch, the switch will only control the luminaire, then the wiring method is as follows: connect the fire line to the L terminal of the switch, connect the L1 terminal of the switch with a terminal of the lamp, and put the zero The line is connected to the other terminal of the lamp cap, and the switch forms a loop with the lamp. Then connect the live wire to the L terminal of the two-hole socket, connect the neutral wire to the N terminal of the socket, and the two-hole socket becomes another circuit.
