I\\\'ve got a new switch with different markings. I have red wire, black wire and green/yellow wire. Also comm, l1 and l2 where do they go ?

what markings did the old switch have? where was earth connected on the old switch?

red to com, black to L1, earth to terminal in backbox

black wire going to comm - L. that being the only marking.

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?

Maybe the black was wired to C by mistake. Or maybe the black is connected to the live loop and the red is connected to the sw terminal.

It doesn't really change anything - it will still break the supply to the
lamp(s).

think about what a switch does - its a simple contact to break a single pole of a circuit. It doesn't matter which way it is wired. wire black to COM if you want.

L2 mark is there in case the switch was produced as a 2-way model.

Yours is obviously a 1-way, hence lack of an L2 terminal.

No offence, but if you struggle at this level, should you involve yourself in this?

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.
