But this switch is not a light switch feeding from the house lighting circuit, it is one I put inline with an old light plugged into the mains, so that I had a simple on-off switch. It worked fine. But I now wish to put in a dimmer instead of an on-off switch.
So all I have are Live, Neutral...
I have a 4 way spotlight fitted to the wall to which I want to connect a dimmer switch. At the moment the lights are just wired directly to a standard plug and plugged directly to a mains wall socket with a standard light switch, connected on the live wire in between.
I have bought a dimmer...
