2 Way Lighting Circuit Wiring Diagram. Old lighting circuit cable colours unharmonised new lighting circuit cable colours harmonised twin and earth cable current ratings. In position 1 when the switch is down or on com and l1 are connected together just like the one way switch.
Pin1 of both the switches are connected with the phase or live wire and pin2 of both the switches are connected with the one end of the lamp. The hot and neutral terminals on each fixture are spliced with a pigtail to the circuit wires which then continue on to the next light. By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load.
The two way switch is used to on off the light fan from two different locations.
This is a completed circuit. Connect the line brown wire coming from the light together with the 3 core earth cable black wire in to the l1 terminal of the two way switch. Before you start safety first. The electrical symbol indicates where power enters the circuit.
