Hello

I have two 120 volt / two speed motors. Each has a high and a low speed.

I am told that there is some sort of three way disconnect that disables the low and enables the high and vice a versa.

Is it as simple as a 3 way switch controlling one leg or the other ?

if the motor has only 3 wires ,a common, hi & low. a 3 way switch would work fine if it can handle the load. just one thing though it want have a on or off. ERWIN
