This is even pretty crazy for OT, but I will try...

I am not an electronics person, so I am going to need some help. I don't even know if there is such a thing.

I have 3 compressors, a small tank, and a 12V power source (these are itty bitty air compressors). (They are all hooked up to the same pressure switch.) What I want is to endurance test each compressor. So I want the power from the source to go to the first compressor. When the pressure switch cuts the circuit, this 'switch' will move into the position 2. When the pressure in the tank decreases (aka the pressure switch is activated), current will now go through the second compressor (because the switch is in the 2nd position) and pull air from it, and so on and so forth. After completed it will go back to position 1 and continue through the cycle again.

Any thoughts? Even possible?
