Need help frind an automated switch relay combo

[SunlitComet]

A while back I had a 12v relay with a multiwire cable going the switch. When 12volts was apllied you hit the momentary switch and the relay latches on until power removed. Once removed and reapplied you would have to hit the button again to activate relay again.

Has anyone else seen these I need to get a bunch for a truck project?

Open to all ideas.

you could use a simple spst switch and do the same thing. just apply power when you wanted and use the hot side of your switch to a switched ignition. would cut power to the switch when the key was off, and power to the relay would have to go through the switch when the ignition was on, so, hang on, i'm rambling. let's take a breath. ok. you could run a switched ignition to the switch, but the switch would have to be on to power the relay. there. something like that.

I get were your going . The thing is I want it to require interaction each time power is back. They would operate like say a factory fog light switch or defroster heater.

I know it is out there so I'm looking at oem suppliers but they usually don't have catalogs online for me to look at.

Dang it, I'm getting old and my memory is not working quite right. I'm sure that a member here just posted up a link to special relay circuits. I clicked through and browsed. I'm sure I had browesed to just a circuit that you need. But I searched here and couldn't find the post.
I remember the URL as being 12volt.com or something.



EDIT: Found the site using my browser history, still can't find the original poster though. The link is HERE. You are looking for the momentary to constant circuit. Props to whomever the original poster was.

Just curious how is this going to be used??

Go to MOUSER. I have a 2200 page catalog from them with just about every damn electrical part under the sun. I had to find a couple of push to rest breakers that came on my 2008 SeaPro boat and they were the only place that carried them but they have millions of electrical parts and diagrams of how big the parts are, what the ratings are, and what not. http://www.mouser.com/

Sorry 99 I have been to that but I am still trying to do it without dual relays. Thanks any other ones you might have seen.

Retorq, most used for lighting specifically to act as decribed by california vehicle code like headlights must be on to allow foglight use kind of stuff. But still reset each power off cycle. Some others I am still dreaming up.


Jaycenk, I am still searching thru Mouser as well. Been at it for days now.

The idea is to have something like the under hood power box that has a power feed, fusing and control relays. Part of my plan includes a bulkhead connector from painless that has 22 terminals to handle up to 12ga. 20 amp max each so beside relay control circuits some alarm related circuits will be there too. To move high amps into the cab for high power alarm circuits and my 5-channel amplifier Painless has some bulkhead pass-thru posts that are rated for 225A. I am also debating an in cab inverter that would definitely need a automated relay so I could not leave it on by accident.

Being an aircraft mech I think like aircraft systems do so this is why I am putting so much development time and ideas into it.

Yea I see what your getting at. Hum... You want a change of state relay. so it dose one thing or the other each time the momentary is pushed? and to defalt to one state when truck is turned off? My wifes 04 grand prix GT uses something similar on her fog lights as it uses a momentary switch on the turn signal lever to activate and de-activate the fog lights. It does not matter if you have them on when you shut the car off. Every time you turn the car back on and the auto lights come on the fog lights are always off. you have to manually rotate the momentary switch on the turnsignal lever to turn them back on. Is this what you are tring to do?

Ok, so no two relay circuits. How good are you at soldering?
I think that your looking for a flip/flop or latching cicuit activated with a pushbutton. Take a look HERE. Or if you like Push on/Push off, take a look HERE. One relay, and various parts soldered.

EDIT: I like the second one because when wired from the IGN, it will not activate until the push on button is pressed, and will stay latched until the IGN source is removed(shutting of the truck) or the push off button is again pushed.

about that.

Just an update I found exactly what I was looking for. Will not order them yet till I have not gotten the lighting systems I want yet . I will have to by them from the U.K. for $80 USD. Still looking for ones here in the USA that cost less

Thought I would just pass it along
