Update:
I went shopping and got the same switches that Niner got
My issue is the those switches are only ratted for 50mA so it will not run a 30A relay. I bought a second relay that is good for 10A @ 120vac/24VDC. The guy at radio shack that it is good for 5A @12vdc. Is this right?
Do I need to have this small relay run the big one? or is 5A good enough for the injector circuit?
