The light switch in the bathroom has failed, it's a domed thingy on the ceiling with a pull-cord; the rocker mechanism inside has snapped.
I've bought a replacement (6 amp 2 way as per the original) but where do the wires go? The earth is obvious but I have L1, L2 and COM connections.
All help appreciated and apologies if it's a no-brainer question but I've never understood this COM malarkey
