I hope this is in the right section, I think so....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
 

I am sure you can get 555 timer in your local store ..
This timer can drive <200mA load, so check if it is enough to directly drive 30A relay ..
Here is info on the 555 timer:

Select the astable option and use the reset pin as start/stop ..
