Multiple 12v switches?


Recommended Posts

Posted

I'm Trying to get some more lighting into the back of my work van as I'm always loading out in the dark. What I'm thinking is to get 2 of the 5m led strips (warm white not that the colour bothers me) and stick one on the roof down ether side of the van which is about 4m long

Now my old van had a switch on the dash that enabled the rear lights. I liked this feature and would like to do it again which isn't hard. BUT this van also has a panel at the back in the top right corner that would allow me to very easily attach a switch which would give me control from the back of the van (the LEDs will be wired to the exciting door lights so I don't loose the door open ability should I want it)

My question is. Does anyone know of a switch or relay or something like that which would allow me to use both switches to control the lights. So I can turn it on at the back. But when I get in the cab and forget to turn it off. I don't have to walk to the back... Any ideas? I thought a relay would be the best bet but I'm not sure about how I go to having two totally separate switches for the same thing

Sorry for spelling mistakes. My iPhone screen is cracked more then a pack of cookies delivered by FedEx is, so can't easily re read what I've typed

Good rule of thump is go by what fuse size is being used in these amps. The higher the more amperage it pulls, this is what I look at.

I'll stick a 300 amp fuse in a potato and sell it to you for $2k.

What you would do is wire both switches exactly the same way to one relay and from the relay to the lights that way either switch will trigger the relay and turn on the lights.

Edit- also make sure you fuse all the power wires.

That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

So do I need to find a switch that wont stay on? just one that can tell the relay to turn on then become idle? would you happen to have a link or know the name of what im looking for?

so far all ive come up with wont allow me to use them seperatly as the switches stay "closed" when its on, there for using the other switch just means I have two closed switches... Unless that isnt whats going to happen and im looking at it all the wrong way

two momentary switches and a relay that accepts a momentary signal...

could even get a delay time relay and set it at a desired time to shut off after triggered-

wonderful! thanks, I tried every variation of what my brain though that word could be lol

momentary... makes sense

why wouldnt you just run a switch to the front to control a relay which has the lights on it? then you could have switches at the back to control each individual strip

I think the idea was to be able to turn the lights on/off regardless which switch used (front/back)...

whereas a constant switch in the front, in the on position, would override the rear switch.... or vise versa-

hmm, so a rear switch and front switch are both masters in a sense? a multiple relay setup with push buttons could work.
