I'm looking for a way to switch 12v constant on and off and with a SPST momentary swtich to switch a 12V accessory on and off.. If there's a product out there that will do this for a reasonable price that would be fine as I'd just as soon not have to build a circuit.

I've done a fair amount of Googling and can't find what I'm looking for but I know it must exist somewhere.

TIA

Would it be feasible to use a premade PCB latching relay to power a Bosch-type relay?. I found one at Mouser that is only $5, is 12V and has a 2amp capacity which should easily drive a Bosch 20A relay. This would save me both time and the hassle of putting together a the more complex latching circuit.

Here's the one I'm looking at:
