This high-quality low-pressure switch is a critical safety component designed for HVAC systems, specifically air conditioners and heat pumps. Functioning as a protective sensor, this air pressure switch monitors refrigerant levels within the system. It is precision-engineered to open the electrical circuit when the internal pressure drops to 35 PSI, effectively shutting down the compressor to prevent catastrophic damage caused by low refrigerant levels, system leaks, or restricted airflow. By acting as an automated cutout, it helps maintain system integrity and prevents expensive mechanical failures. This replacement switch is essential for restoring reliable safety monitoring and air-proving performance to your residential or commercial cooling equipment.
