i have a 2 core and earth cable going to my single switch it has l1 l2 and c on the back i can wire the 2 core into the l1 and c but there is no where for the earth as it is in a plastic pattress box instead of a metal back box so no where for the earth to be clamped however i noticed the sheething is overshot on the earth making me think it was never wired in in the first place is this safe
