This high-performance low pressure switch is a vital safety component for HVAC and commercial refrigeration systems. Functioning as an air proving switch, it is designed to monitor system pressure and protect the compressor from damage caused by low refrigerant levels, leaks, or restricted flow. The switch features a precision calibration, opening at 7 PSI and closing at 22 PSI to ensure the system operates within safe parameters. Its 1/4 inch female flare (.25FFL) connection provides a secure, leak-resistant fit for standard refrigerant lines. Ideal for maintenance and repair, this pressure control helps prevent motor burnout and extends the operational life of cooling and climate control equipment.
