How to wire 2 'push to break' door switches to 1 LED driver

[karlrees]

Hi all,

I've just made a cocktail cabinet with two doors and a central division. The client wants an LED strip light to turn on when either of the doors opens.

My plan was run a single length of LED strip light along the cabinet through the central divider and run it off the one 12v driver.

In theory, by opening either of the two doors (or both), push-to-break switch on either door would turn on the light.

My question is, how do I wire up something like this?

To re-iterate, I've already got:

One 12v LED driver
A strip of adhesive LED lights and connecting lead
Two push-to-break door switches.

Thanks in advance for any assistance.

Both door switches in parallel with each other, switching the mains supply to the LED driver. I would not switch the output of the driver.

Thanks for your reply.

I understand the theory of this (rather than it being in series), but do you happen to know of a diagram which would help me to wire this up? Will I need a junction box or two to put in the second switch?

Sorry - I'm a cabinet maker with very little electrical knowledge.

Probably best to fix the driver to the rear of the cabinet, and a J501 joint box next to it.

Then take a 3 core 0.75mm flex from both switches to the joint box (individually) and the same sort of flex from the plugtop to the joint box.

Ah-ha. It's becoming clearer now. Still a bit of head scratching to do, but I think I'll get there.

Thanks again for your help.

Earths in the empty terminal, although if your switches do not require an earth and the driver does not require an earth, you could just use some two core flex instead.

that's brilliant. Thanks! Yes, they've just got the two core stuff I think - no earth.

Thanks again.
