Product Details

Description

This premium High Pressure Switch is a vital safety component for residential and light commercial HVAC systems. Designed to protect the compressor from excessive internal pressure, this SPST (Single Pole Single Throw) switch monitors the refrigerant line and interrupts the electrical circuit if pressures reach a critical 650 PSI. It automatically resets or 'closes' once the pressure drops back down to a safe 550 PSI, ensuring your air conditioning or heat pump system operates within safe mechanical limits. Featuring distinctive red leads for easy identification and wiring, this switch is an essential replacement part for resolving high-pressure cutout issues in modern AC units and cooling systems. Investing in a reliable pressure proving switch helps prevent permanent compressor failure and extends the overall lifespan of your heating and cooling equipment.
