Description
A pressure switch is an electrical contact device that opens or closes a circuit based on the pressure of a medium (gas or liquid) against a piston or diaphragm. Used widely for pump control, safety, and HVAC, these switches maintain system pressure within a set range by turning devices on/off, frequently with adjustable pressure limits
Mechanical Pressure Switches: Utilize a diaphragm, bellows, or piston to counteract an adjustable spring force. They are known for reliability in harsh conditions, particularly for pneumatic and hydraulic systems.
Electronic Pressure Switches: Offer greater accuracy, higher switching cycle counts, and minimal contact wear compared to mechanical counterparts.
