Hi checked the past threads. I am repalcing a 2 way switch with a chrome one. Just wanted to know how to wire to the new switch. The existing switch has wires going to to the L1 L2 and com as well as a wire directly from L2 and com. Also the earth is currently directly connected to the metal box, do i need to change this and wire it to the new plug. Sorry for the number of questions...any help gratefully appreciated
