How many T&Es are in the existing switch ? (unless there are two, I
think this might be a non-starter - and even then...)
There is only one T&E from the existing switch. However, it would be
easy to add extra cable(s) going from the rose to the hall switch, as
the hall switch wires run down inside a wall cavity. (No chasing
required)
Basically you're looking to try to get this:
switch1 ___/--------------------\____ switch2
live from lamp \--------------------/ switch to lamp
*
...but you need a spare core to the first switch to act as the
"strap" to the second switch as you're wiring from the centre* not end
to end.
Then, if you can get a three-core&earth to the second switch from the
ceiling rose, two cores are the strap wires, the third being the
switched live - you can hopefully get creative with a connector strip
:-}
I wonder if anyone makes a more elegant solution in that the second
switch doesn't need wiring at all - it'd be a battery powered RF
device that signals the other to switch electronically...
I'll look into those. Thanks for the suggestion. Thanks also to the
others who responded.
