What would you like to use, a toggle or rotary switch?

You need a single pole - double throw with center off position switch (center off because that is common). You could also use a three position switch like a Jeep wiper switch or 3 position fan switch. You wire the load to the common lug and the different sources to what is normally the load lugs.

I would assume your temp sensor provides a ground when the set temp is reached. That means you need to wire +12v power to one side of the relay. Wire the other side of the relay to the common lug on the switch. Wire your temp switch to a lug and wire the remaining lug to ground.

There are 10 kinds of people in the world.
Those who understand binary and those who don't.
