Hi, I’m changing a ceiling pull cord switch that operates two wall lights as the existing one has disintegrated. There are 3 wires that need connecting. 2 red 1 black. The new switch has the following 3 terminals L1 L2 and L . Can anyone tell me the correct wiring for this fitting please?
I’ve tried red to L1, red to L2 and black to L but that hasn’t worked.
