Can anyone explain how to wire up this 2-way switching?
The existing setup: A lounge with one ceiling light controlled by one
wall switch. Cables are twin & earth.
What I want to do is run a cable from the *ceiling rose*
lounge to an existing light switch in a hallway leading off from the
I then want to replace the hall switch with a dual-gang switch. I want
one side of the new hall switch to control the hall light, and the
other side to control the lounge light. The original lounge switch
must behave as before: switching the lounge light on and off.
I'm guessing this is dead simple to do, but would be very grateful for
a link to the relevant wiring diagram, or alternatively, worded
instructions. Thank you in anticipation...
An alternative solution would be to run a cable from the lounge
ceiling rose to a second single-gang switch in the same room, so each
of teh two switches in teh room can then turn the light on and off.
