Hi, I am trying to wire a two speed switch to a three phase motor. I have continuity checked the switch in both positions 1 - Low and 2 -High (See attached) Can someone confirm if this is correct and would this change the speed. Secondly i have a cable coming from what is I assume from the delta overload contactor and a a cable coming from the back of the wheel head motor switch (see attached). Where on the switch do these two wires get connected.
