I have a Bulgin push button switch that is NO and momentary, it is also has an illuminated ring. I want to use several of these in an install to activate 4 sets of PIAA off road lights(front, left, right, rear). Its not just a matter of the latching effect but I can't figure how to activate the LED ring in conjunction with the lights. Can anyone help with this? Thanks, Justin

So I was trying to find an answer to this question but it seems like the only one on the site is the one that uses 4 or 5 relays(to many for my space constraints) or the one using the latching relay(have trouble figureing if this one would work or not.)

Now I was looking at the wiring for the PIAA 525 Driving lights which have a low and high beam. they are controled by a small switch module that is just two momentary switches one for on and off and one for high and low modes. But the wiring only includes two relays....Anyone know how they pull this off? Or how I might duplicate it with my own push button switches? 

Or am I just missing something obvious?

Thanks, Justin

The control box most likely contains a processor that turns the momentary pulses in to latching on/off pulses.  The processor would then drive a transistors that would run the two relays - one relay for high, one relay for low.

It would be a pretty straight forward set up.  Where did you purchase the push  buttons from?  I've been looking for some nice illuminated momentary push buttons.

I opened up the switch module and all I see on the PCB is the two switches and the two LED's, no sign of any processor's. Could you explane more about this straight forward set up? I really would like to use these switches and I'm having a really hard time tracking down their latching cousin's. Can anyone provide a link to a good latching relay for this set-up?

This is the picture of the switch provided by your link. It is wrong .

Here is the correct Diagram

As for the relays here is how it is done.

Thanks for the info, very through,

...so the only way to do this is with two switches for each light? Guess I won't be using that switch after all...

Also how is that diagram any different that yours other than the added LED info?

The only way to use push button switches and bosch style relays is the way above.

If you want to get more invovled you can do it with latching relays, flip flops, microcontrollers, etc.

How much more involved would it be to use latching relays? What kind of latching relay would I need?

Can I modify the Single Pulse to Lock and Unlock on https://www.the12volt.com/relays/page5.asp to do what im looking for? If so where can I find that relay?

I really want to use these switches its for a very unique panel on an install that I'm working for...I found the newer latching version of the switches but they are 18mm insted of 22mm and the button is hard to push.

I'm thinking I might try and modify one of the Pilot tactile switch boxes to work with 4 of my switches but im still trying to figure that one out..... 

Thanks for all the info everyone......
