Switch Loop Wiring Diagram Two Switches. From the wall switch a 2 conductor cable is used to provide power to two electrical receptacle outlets. If its a two way switched circuit theres normally three wires going into it to the 1 2 and c terminals with possibly two others going to the loop terminal.
Lets have a look at a basic circuit diagram describing two way switch wiring. The out cable continues to the next light. There will only be three wires at the light live neutral and earth.
2 the return live switch wire from the light switch.
Step by step. Now connect the loop of the black wire to the terminal at the bottom of the switch. The two way switch circuit is simple. Lets have a look at a basic circuit diagram describing two way switch wiring.
