The original wiring is as shown ..used a new switch it works ok off one switch turning both lights off .But on the other switch it will not turn the lights off they just stay on and sometimes one switch turns both lights on ..both commons are correct i am not sure if the other wires into L1 and L2 are correct any ideas please .i swopped the the L 1 and L2 around separately it was just the same but i did not try them both together

I think you have mixed up the COMs - which used to be A & B.

It looks like you marked the bottom wires with a pencil and it appears (although not clear) that you have the red with pencil mark in the wrong switch.

You do realise the original switch is two triangles, A & B; not top and bottom?

Ok i didnt realise they were triangles ..so if i swop the commons over it should be right.?
And then for the second switch ( which i havnt done yet ..just copy the first one ..?
Thankyou very much it is much appreciated ..i will let you know the result ..

I think so.

Well, copy what's in the second switch, yes.

Hi i swopped the commons over and it works fine now. The 2nd switch is slightly different it has L1 common L2 and L3..so is it L2 would be L1 on the new switch and L3 now L2 .thanks again

I think you have written that correctly.

Com......L1
L1.........L2
L2.........L3

It's still two triangles, whatever the markings.

So faced with terminals labelled A, A1 & A2 and B, B1 & B2, and with raised mouldings tying A, A1 & A2 together and B, B1 & B2 together, you didn't think that A, A1 & A2 were related to each other in some way and not to B, B1 & B2.

You really, really must pay more attention, and THINK.
