courtesy light replacement 3 way switch

[jimjones235]

I'm replacing the internal lights in the rear with LED downlighters and want to put in a 3 way switch. I've got the courtesy lights with 3 wires (+ve, perm -ve and timed -ve). The way I'd go about this is connect +ve on lights to +ve wire, -ve on the lights to common on switch and perm -ve and timed -ve to the two switched connectors... all good... but the switches I've got suggest something totally different, which I think is confused by the fact they have an LED in them.

Here is diagram:




I guess the switch is designed to run off the +ve not negative, now, a switch is a switch so probably shouldn't matter, but in this case as it's running an internal LED it's left me scratching my head.. It's compounded by being a DPDT switch (so two circuits). Any suggestions for how to wire this up?



As an aside I'm bemused as to why they switch the -ve - always thought better to switch the +ve.....

LED rear interior lights - How i done it. so a few have asked, so i though i would just list it here as a post so i could refer back to it in the future. The lights were purchased from The T6F shop over here > We were planning to do the carpeting at around the same time, but for the purpose...

Thanks Dellmassive, I had read that, but it talked about standard setup (which I get), and leisure battery (not relevant to me) was just this switch which is confusing me

I wonder if the internal LED runs from from one of those circuits or whether they are bridged internally... If it ran from just the bottom one I could connect:

perm -ve to 4
light -ve to 5
timed -ve 6
+ve to 2
and perm -ve to 7 (or bridge from 4)

Ok, just reread the other thread and realised I'd totally misread existing 3 wire connections. And it's a timed +ve, and perm -ve, and switched -ve. Still not 100% on this switch though..but maybe I'm just having a mental block..

Show us a few pics of ur switch.

If pin 2 and 5 on the switch are not common you’ll be ok. Permanent +12v to your lights and pin 2 of the switch. -ve from your lights to pin 5, permanent -ve to pin 7 and pin 4, timed -ve to pin 6

Yeah, ok got it.. if they are common then it'll be pretty obvious (light won't go out) I guess..

If they are common, you’ll pop a fuse . You could always dismantle the switch and solder the leds the other way round . I did exactly this on my main switch panel. It took me 3 switches to get it right though
