A pressure switch monitors system pressure and activates or deactivates an electrical circuit when a preset pressure level is reached. Inside the automatic pressure switch, a sensing element such as a diaphragm or piston moves in response to pressure changes. This movement mechanically actuates a microswitch, opening or closing the circuit. Adjustable pressure switches are widely used for pump control, alarm triggering, and system protection, ensuring processes operate within safe and efficient pressure ranges.
