I've looked at lots of threads but can't find the answer to this... I've tried to replace an old two gang two way switch with a new one but can't get it to work. The old one has terminals simply labelled 1, 2 and 3, but the new one has terminals labelled COM, L1 and L2 (for each of the two switches).
There seem to be too many wires - I've taken a picture in the hope you can help me know which should go where, I've tried several wiring diagrams and none seem to work. The other switch in the circuit just has 4 wires instead of 7 here - reds into COM and one of the L1s, blue in the other L1 and yellow in L2. As you should be able to see, the blacks are joined up already by a connector on each side.
Thanks in advance.
