Controlling AC Motor with Relays
I am not entirely sure I parsed your question correctly, but...
The circuit below uses a DPDT (double pole, double throw) relay.
If the coil in the circuit is un-energized, the red wire will be connected to blue, and the black to the yellow.
If the coild is energized, the red will be connected to yellow, and the black to the blue.
Note that if one of your relay contacts becomes &quot;sticky&quot;, you may create a short when the relay coil changes state, so it is best to fuse both the red and black wires, or the blue and yellow wires.
