Pressure Switch

A Pressure Switch is a mechanical or electronic device activated by the pressure of fluids, air, or gas when the fluids, air or gasses reach a threshold or setpoint. The designs of pressure switches include bourdon tubes, pistons, diaphragms or membranes that move or deform with the amount of pressure exerted by the system.

The components of a pressure switch are connected to one or more contacts in the switch. With enough force, a contact closes or opens the switch depending on its configuration. Although pressure switches have a variety of methods used to detect pressure, they can be primarily categorized as electromechanical or electronic.

Pressure Switches are used in most industries employing compressed gas systems, HVAC, instrumentation systems, pumping systems and so on.
