Light switch help

[Chris Joyce]

A bit of electrical help if possible please.

I have five led lights in the van, I would like to put a simple rocker switch in the b pillar near the sliding door to turn them on/off, I also have a cbe dimmer switch in the kitchen are which I’d like to use to dim them and turn them on/off.

Is this possible?

and if so which is the best way to connect them up?

thanks in advance.

Are they to run from a leisure battery or your existing courtesy light circuit?

The leisure battery

You could connect both switches to the lights in parallel. just bare in mind that if you turn the lights on with the switch you won’t be able to dim them or switch them off with the dimmer. Similarly if you turn them on with the dimmer you won’t be able to turn them off with the switch.

To confirm is your dimmer one of these? https://www.12voltplanet.co.uk/user/downloads/CBE-Electronic-Dimmer-Instructions.pdf

It would be quite easy to interrupt the feed to the dimmer and either switch would turn off the lights, but both switches would need to be on to get the lights back on again so you could get yourselves in a pickle

The leisure battery

Do you want them to operate as courtesy lights as well or purely a leisure battery fed system only?

@Deaky I've had a play with a circuit diagram creator. I am not entirely sure how the Pos, Neg and Load connections of the dimmer are supposed to be connected but would this work?.....(I couldn't find a proper DPDT relay diagram).

In theory yes, but because the courtesy circuit is dimmed it might cause the relay coil to chatter. Someone posted a solution using a arduino relay board that should solve the problem

Yes, I do remember seeing that. Cheers.
