Pressure switches monitor fluid or air pressure and trigger an electrical contact at a preset setpoint. Used in hydraulic systems, air compressors, pumps, and HVAC equipment. https://www.marketresearchfuture.com/reports/pressure-switch-market-6823 Types include electromechanical (diaphragm, piston) and electronic (solid-state). Challenges include setpoint drift and contact wear. Nevertheless, adjustable deadband, high cycle life, and explosion-proof enclosures enable reliable pressure monitoring in industrial, automotive, and residential applications.
