Switch

Pressure Switch: A device that senses a change in pressure of a gas or liquid, and actuates an electrical switching element when a pre-set pressure point is reached.

Things to Consider When Purchasing This Product:

Switch type considerations of: poles, throw, normally open or closed; Approvals such as UL, CSA; Voltage and current limitations; Power consumption (for low differential pressure switches which operate on capacitive principle and use solid state circuitry to process pressure signal); Temperature range; Setpoint accuracy (at standard temperature); Repeatability; Hysteresis/Deadband; Materials of construction: body, diaphragm, contacts, springs, terminals, pressure connection, adjusting screw, media chemical compatibility; Cycling limitations (cycles/min) Dimensions; Weight; Enclosure or housing type (NEMA rating); Sensitivity to mounting position or shock/vibration; Warranty
