Pressure Switch

What is a Pressure Switch? A pressure switch is a simple electromechanical device that is triggered by pressure to turn an electrical circuit on or off. The pressure point that activates the switch is called its set point, and the pressure threshold that deactivates the switch is called the cut out point.A Pressure switch is a two-part device consisting of a sensing transducer and an electrical switch. The electrical switch opens and closes at a specific pressure often referred to as the Setpoint. Depending on the switch and the vendor, the switching pressure setpoint may be fixed or adjustable.
