This premium High Pressure Switch serves as a vital safety cutout for HVAC and refrigeration systems, ensuring your equipment operates within safe pressure limits. Designed as an air proving switch, it monitors high-side system pressure to prevent damage to the compressor and other critical components. The switch is engineered to automatically open the circuit when pressure reaches 405 PSI and reset (close) once pressure stabilizes at 300 PSI. Whether you are performing routine maintenance or repairing a non-functional cooling unit, this pressure sensor provides reliable protection against system over-pressurization, helping to extend the lifespan of your appliance and improve overall safety.
