Hi,

The switch will connect to the black wire and break that connection to the motor.

It's not that simple, there are three wires coming from the 120v supply to the switch and 3 wires going from the swith to the motor. In what order are they attached?
Expert:  Mike G. replied 5 years ago.

The sketch shows that only 2 feed and 2 load wires are attached to the pressure switch and the ground are connected together and to the ground screw. The connection is paired on either end of the switch as shown.
