This high-performance High Pressure Switch is a vital safety component for HVAC systems, specifically designed to monitor and regulate refrigerant levels in air conditioning and heat pump units. Functioning as an air proving and pressure-sensing device, it protects the compressor by automatically interrupting the electrical circuit if internal pressure exceeds safe operating limits. With a cut-out set point of 650 PSI and a reset point of 420 PSI, this switch prevents system failure and mechanical damage due to overheating or blockages. It is an essential replacement part for maintaining the longevity and efficiency of residential and commercial climate control systems, ensuring they operate within designated pressure parameters.
