Pressure switch

Pressure

A pressure switch is a device that operates an electrical contact when a preset fluid pressure is reached. The switch makes an electrical contact on either pressure rise or pressure fall from a certain preset pressure level. They are in a wide range of industrial and residential applications like HVAC systems, well pumps, furnaces, etc. In the industry, pressure switches are one of the most commonly used fluid control components used in numerous industry verticals for controlling operations and process optimization. They should not be confused with a pressure transducer. A pressure transducer converts pressure into an electrical output signal.
