Hi
I'm looking at installing some more zwave network controlled switches which i've done many of in the past, but i've come to the latest light that I want to enable and come across some wiring that i'm not entirely sure how it works. I'll try any explain the best I can.
The switch I am looking at is a 2 gang switch. 1 switch is part of a 2 way switching set up for a lighting circuit that I'm not interested in right now. The other switch controls the lighting circuit i want to enable. This switch has the normal wires I would expect, old colours blue and red for live and switched live. That wouldn't be a problem if that was it, except there is another short "bridging" wire that connects from L1 on the other switch, to COM on the switch I am interested in. I can't work out what this does or what its purpose is given that these are 2 separate circuits. Obviously the 2 lights are working and being controlled as i would expect now, so it must be a valid wire, but if someone could explain why it's there, that would be great.
Thanks
