Lighting re-wiring solution

by stodman » Sun Dec 24, 2023 3:40 pm

Hi all,

Looking for someone to help with this dilemma. Image attached to try and explain it better.

We have 3 separate lights currently controlled by 'Switch 1', on a 3 gang switch. It's a live feed into the switch straight from the consumer unit, then 1 cable going from the switch, to each light respectively.

We're looking to move the controls for light 2 and 3, into a new 2 gang switch in another room, whilst keeping light 1 controlled by switch 1 on a single gang now.

The issue is we only fed 2 cables up the wall during the planning phase, from the new 'switch 2'. Those two cables are now going from the switch to the loft. What's the best way to connect these up to the existing wiring structure, so they could control light 2 and 3, independently?

If we had 3 cables fed up it would be easy - I'd have one live feed coming into switch 2 from switch 1, then the two cables going to light 2 and light 3 respectively, but struggling to understand how it can work without needing a 3rd cable. It's too late to get a 3rd cable down, hence the issue.

Any help much appreciated!

It would appear that who ever installed the new cables intended they should be used as feed and return for lights two and three. That will work, providing the existing switch is bypassed.

Have you looked at smart relays, switches, and bulbs. I have given some examples in the other forum where you have asked same question.
