If I us a Magnetic Starter and I have a new 5 hp 2 stage Rol-Air Pump, is it still best to use a switch like this that has the unloader valve built in?

A: It is always best to use an unloader, so the motor doesn't have to start the compressor against pressure.

Will this pressure switch work with a 5 horse motor?

A: It the starting current draw exceeds the 25 Amp limit of the switch contacts, the lifespan will be reduced. When used with true 5 Hp motors which can draw 22.5-25 Amps (230 VAC) while running, it is usually best to use a magnetic contactor that is controlled by the pressure switch.
