UK 2 wires at light switch?

[Chocolate123ba]

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?

I haven't at the moment it's in a different house but it's just got 2 cables one for l2 and one for Common?

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.
