UK 2 wires at light switch?

Chocolate123ba · Mar 31, 2020

Hi, I've only got 2 cables to my light switch, no earth. Does this mean I cant have a metal face dimmer switch in replacement for the plastic one that's already on?

check that the earth conductor may be there. it could either be connected to the back box or cut off. is it T/E cable or 2 singles?

you'll probably find that the lugs for the faceplate pins are nylon, common wher there was no cpc on lighting, (1960's?). therefore you have a choice of using class II switch or supply an earth.
