Hi I have a single 1 gang switch that turns on two lights together, now I want to replace it with a single 2 gang switch to control both lights individually.
What I found behind the switch are 7 coloured wires. 1 red by itself, I know it is the live wire. Then three (red, green/yellow, black) from one light and another three from another light.
How they are currently connected is like this: the single red live wire into one slot, the two red wires from the two lights are twisted together into another slot. Then the two green/yellow wires are twisted together and the two black wires are twisted together.
In order to separate them, how do you connect them so that:
Option 1. each gang control each light
Option 2. light B can be controlled only when light A is on (i.e. if light A is off light B always off)
