Is it a single pole switch, or a (220)240v switch? A 240v switch is a double pole switch. It has 4 screws and disconnects both hot sources simultaneously.
If it's a single pole 120v/277v switch, that just means you can use it on 120v or 277v circuits. If it's not a double pole switch with 4 screws, it's not the right one. Get a 240v double pole switch for this. You can usually find these at home improvement stores.
When you state that the motor is a "three wire" make sure that the phasing is correct and you are not trying to connect up a three phase motor.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized

The switch will be wired in series with the motor. It is connected between the supply voltage and the motor's junction box. The switch will break the black wire while the white wire is just wire nutted together and is carried directly through to the motor.
To wire a toggle switch to your wiper motor, first, identify the motor's power and ground terminals. Connect one terminal of the toggle switch to the power supply and the other terminal to the wiper motor's power terminal. Then, connect the ground terminal of the motor to the vehicle's chassis or a suitable ground point. Ensure all connections are secure and insulated to prevent short circuits.
To wire a sunroof to an aftermarket switch for a 1995 Lincoln Continental, first, disconnect the vehicle's battery to ensure safety. Locate the sunroof motor and identify the power and ground wires, typically using a wiring diagram for reference. Connect the power wire from the sunroof motor to one terminal of the aftermarket switch, then connect the other terminal of the switch to the positive battery terminal. Finally, connect the ground wire from the sunroof motor to a suitable ground point on the vehicle, and test the switch to ensure proper functionality.
It can depend on the make of the vehicle. On a Chrysler product, the switch provides ground.
I,ll figure u have no idea how the motor works. That,s how I started. The ignition has a coil and points. There is a central contact for the points and coil. U have to connect a ground wire to this point so when the motor is running and u ground that point it kills the motor. Any questions e-mail me!
if you are using the pressure switch to control a 3phase pump chances are it already has a magnetic starter and a single pole control circuit i have seen small 3phase air compressors with the contacts driven right off the diaphragm bigger ones usually have 110 volt controls i would be concerned about the current rating of the switch if you are trying to switch the motor directly there are many single phase compressors that run directly from the pressure switch
the motor should have two leads, usually a black and a white. connect the white to the fusebox and the black to a ground.
To wire a Salzer control switch to an A.O. Smith motor, first determine the wiring configuration of the motor (e.g., single-phase or three-phase). Then, refer to the wiring diagram provided by both the motor manufacturer (A.O. Smith) and the switch manufacturer (Salzer) to identify the appropriate connection points for the power supply, motor leads, and ground. Finally, follow the instructions carefully to ensure a safe and proper connection between the switch and the motor. If in doubt, consult a professional electrician.
Disconnect wires from motor and check to see if you have power and ground going to motor--if so motor is bad if not have to check wiring and switch to that motor
There is only one ground wire needed on any motor, single or three phase.
remove door panel check to see if you are getting power and ground to motor. If so, bad motor--if no power to motor, check to see if you have power to switch if so ,bad switch--if not bad power feed to switch close but if the switch not on, you never get power to the motor.
Assuming you want to switch a single phase motor, (such as in a residence), you simply have to connect the switch to the incoming power feed. The outgoing, or "switched power" lead then goes directly to the motor. Note the neutral (grounded conductor, the white wire) and ground wire do not switch but connect directly to the motor. Do not use a residential light switch for this application. There are small switches designed to turn motors on/off. The switch must be rated high enough for the amperage and horsepower of the motor. The amp rating and HP are stamped right on the metal base of the switch. Remember, the switch you install must be in an approved electrical enclosure, not in "open air" to be safe from shock hazard or fire. Use an electrical junction box or mount it right in the unit by the motor if that is convenient. These parts are available at hardware stores. If by chance you're trying to switch a three phase motor, post another question providing the horsepower of the motor and its application, as this may require a motor starter (contactor). As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.
