Product Details

Description

This high-performance Low Pressure Switch is a critical safety component designed for HVAC and refrigeration systems. Engineered to protect your compressor from damage caused by low refrigerant levels or system leaks, this air proving switch monitors internal pressure to ensure safe operation. It features distinct yellow leads for easy identification and installation. The switch is calibrated to open the circuit when pressure drops to 25 PSI, preventing the system from running under hazardous conditions, and automatically closes at 41 PSI to resume normal operation. Essential for maintaining system longevity, this pressure sensor is a reliable solution for air conditioning and heat pump maintenance and repair.
