Usually the family electric wire has the fire line, the zero line and the ground three. When installing project switch socket, must distinguish first give these 3 lines. The outer plastic of the ground wire is yellow or green, the fire line can be measured with an electric pen, it is best to mark, the rest must be the zero line, also make the following mark.
If the project switch socket is only used to control the switch of the lamp, we can put the fire line access to the L terminal of the project switch socket, connect the L1 terminal of the engineering switch socket with the wire and a terminal of the lamp holder, the zero line access to the lamp holder another wiring column, so that the switch and the lamp form a circuit. Then the fire wire is connected to the L terminal of the two-hole socket, and finally the zero wire is connected to the N terminal of the engineering switch socket, and the two-hole socket forms another circuit.
If my engineering switch socket is used to control the switch of the power socket, we can put the fire line into the engineering switch socket L terminal, and then connect the engineering switch socket L1 terminal and two hole socket L terminal, and finally the zero line into the engineering switch socket N terminal column. The above wiring method is correct, I hope you can cause everyone's attention.
