Hi,
The ceiling switch for my bathroom light (pull cord) recently broke, and I would like to replace it. I have obtained a new switch which seems pretty similar to the old one. I have three wires coming out of the ceiling: red, black and green/yellow (earth). The red wire is in a terminal marked "L1". I can't make out what the black wire goes into.
Does this setup ring a bell? Will it be a problem switching over to the new pull switch? I have a fair bit of experience with DIY, but not with any mains electrical stuff, so I was wondering how safe this was all going to be....
Many thanks, Mike
