Relays to control lighting in a domestic house.

[Tony Way]

Hi all

I'll freely admit, I'm out of my depth here.
I've been asked to sort some lighting in a bathroom do do the following:
Main lights and some accent lights from one switch.
Mirror lights and the same set of accent lights from another.

I guess it can be done using 230v relays, but haven't a clue how to go about designing the circuit and specification of relays etc.

Can anyone help me through it?

Mnny thanks

Tony

No chance of asking them to use 3 switches, lol

Would love to, but no, they have to do it the difficult way. Once this customer has his mind set on anything, it would take dynamite to move it...
Hence, I have to find a solution.

No relays required.
Use 2 double pole switches.

Can you state on or off for the above table of possibly configurations

I'm struggling a little with that one. Switch isn't powered and I only have 2x 2core to play with.

3 lights. Main, mirror and accent.
1 standard 2g 2w light switch.
Configuration:
Main / Accent on or off
Mirror / Accent on or off

With the probability of both on at same time. - So
Sw1. Sw2
Up Up All off
Up Down Main off - Accent on - Mirror on
Down Up Main on - Accent on - Mirror off
Down Down Main on - Accent on - Mirror on

Hope this makes sense

Agree with this, just loop the accent lighting across and don't switch the neutrals. Click minigrid would work well here with the MD018 double pole modules.

Ok, so you only have 4 wires to play with.
Are these 2 switches separate or in the same switch unit? (2 gang unit)

Looking at James' drawing and drawing it out myself last night, I can do it with the minigrid and the two T&E cables I have.
Many thanks all.
