I have a one way dimmer switch which has two black wires coming from it and it insists, as it is a brass front, I connect an earth wire to the screw on the back of the plate.The light switch has at the top the number 1, with a blue and red cable going into it. Opposite that is a 2 with two red cables. and at the bottom a yellow cable.
It also has two green/yellow cables going into the metal back box.
I am assuming this is a two way switch and therefore the one way dimmer will not be suitable for the job.
Also, any advice on the earth cable would be appreciated as I do not know whether I am to just connect the earth cables from the box or need to supply other cable. attach
