Hi
I am trying to change the plastic white switches & sockets fitted during our recent renovation for some brass ones. All good so far apart from this 2 gang switch:
This controls a wall light and a ceiling light (Both independent, this is the only switch for them)
Wiring it seems pretty straightforward:
Live from the mains goes into L connectors at top. One per switch
Live to light goes from the L2 connectors at bottom One per switch, presumably as each only controls 1 fitting in the room
What is confusing me is a wire that bridges the 2 top L connectors together. Why is this given both appear to be powered anyway? Do I need it?
The switch I am fitting has the same configuration as this, except what is labelled as L in the photo here is labelled as COM (Common) on my new switch.
Thanks for any help you can give!
