This high-pressure switch is a critical safety component designed for HVAC and cooling systems to protect the compressor from damage caused by excessive internal pressure. Engineered for high-performance reliability, this air proving switch monitors refrigerant pressure levels, automatically cutting the circuit when pressure reaches 610 PSIG to prevent system failure. Once the system cools and pressure stabilizes at 420 PSIG, the auto-reset feature restores functionality without manual intervention. Ideal for commercial and residential air conditioning units and heat pumps, this durable pressure control switch ensures your HVAC equipment operates within safe parameters, extending the lifespan of your cooling system.
