Hi maybe someone can help me, im looking for a pre-built circuit / device that is readily purchaseable (from perhaps like an electronics hobbiest site) that uses a momentary pulse signal to switch on and off a 12 volt bosch type automotive relay.

So basically, im looking for a small device that when I push a momentary button, this circuit switches the relay on and off.

now I know how to build one, thats not the issue....finding a pcb / circuit that is pre-made already where i can just hook up a tiny 1/4 amp momentary switch of my liking and a 12v DC 30 amp rated bosch relay is what I am looking for...

if someone can direct me to site that sells something like this, id appreciate it.

Thanks

Digi-key sell latching relays. Might even have one that would just be a drop in replacement for the automotive relay. Just doing a quick search I found G6AK-474PSTUSDC12-ND
which is a 3amp latching relay which would probably be more than enough to bootstrap your automotive relay.
