I need a 2 source - 12 Volt switching circuit

The closest circuit I have seen is the schmitt trigger.

If 12 volt source A is turned ON, then 12 volt source B is turned OFF,

else 12 volt source B is turned ON.

Any ideas? Thanks

What are the sources? You might be able to do it with just a diode. Otherwise, how about a relay?

Relay spst-no + spst-nc 5a 12 vdc

Yes, this relay will work.

I was checking to see if there might be a solid state circuit that could do the same thing.

Thanks for your input.
