I've got it sorted, cheers. I've changed loads of plug sockets and flick light switches but not one of these before. Just was'nt sure because it was wired different from instructions and your advice.
I just like to be sure when messing with electricity.
on the new one L2 has nothing for the wire to go to. Only com and L1 have the screw connectors. The other connector is inside the base which I new was for earth. So red to comm and black to L1?
Why does the black go to comm - L on the old one?
