Cable d fig 2 is a three core and earth this is the 3 wire control that links the two light switches together. One wire connects to com and the other wire to l1. However in this guide we ll focus on the lighting circuit wiring.

Just like any loop in loop out radial circuit the switch cable from the ceiling rose contains two wires a permanent live and a switched live. This is usually a distribution board of some sort. The red wire from the feed cable is connected to the top terminal the red wire going to the light is connected to the bottom terminal the black wires from both cables are connected together in a plastic terminal block and the earth wires are connected to the earth terminal.

How to wire light switches. One way switching plastic switches. This is cable c below one wire connects to l1 and the other to l2 on the top switch.
