This is a specially designed replacement part made for use with air compressors. It is supplied directly from original manufacturer and it is sold individually. The pressure switch helps to control when compressor should start or stop building up pressure. Commonly if your air compressor is not turning off and on at the specified pressure, replacing pressure switch should resolve the issue. Please note this pressure switch is only designed to work with 120V. You would need a set of wrenches, nut driver set and a thread-sealing tape to complete this repair. • First make sure to unplug air compressor • Drain the air tank • Remove the tank pressure gauge • Disconnect the pressure switch tube • Remove the pressure regulator assembly • Disconnect the wires • Remove the safety valve • Remove the old pressure switch • Install the new one • Reassemble and test the unit

Removed electrical connections first from the malfunctioning pressure switch followed by removing the malfunctioning pressure switch. Replaced malfunctioning pressure switch and then reconnected the electrical connections.
Disconnected the wiring, rubber hose, and steel tubing. Removed the switch from the air tank. Replaced with the new switch and attached the wiring, rubber hose and steel air line. All went well.
Removed the old unit from the compressor and bolted on the new switch. The part was a perfect match to the old switch.
After installation the unit worked as new. Have not had a problem with it
