I replaced my old 2HP pump today and when opening the old toggle switch box, there was a fair amount of corrosion on the toggle switch. I picked up a two pole (30A) switch which showed the two hots connect to the bottom two screws (one on each side) and then the switch activates the two legs from the two top screws (one on each side).
The old switch I pulled out was wired like a common 115V with two hots on one side, and then the legs on the other.
Am I missing something? I wired it up as the manufacturer diagram. I can always check to see if both legs are dead when switched off, and both live when on, but I figured I'd ask here before throwing the breaker in case the pump could get upset if it sees only 115V of one leg, if I'm missing something.
Here's the wiring diagram, and how I wired it. The Load here would be the pump.
