Description
The Daikin-McQuay 2534983 High Pressure Switch is a safety control system used to monitor refrigerant discharge pressure in equipment. It is designed to interrupt or signal the control circuit when pressure rises beyond a preset limit, protecting compressors and related components from operating under excessive load conditions within HVAC systems. The switch is mounted within the refrigeration line or control assembly and connects to the system electrical circuit for automatic response during abnormal pressure conditions. In systems within air handling units, rooftop units, and packaged cooling equipment, it is used on high-pressure sides of the refrigerant circuit to support better operation of cooling cycles in commercial and industrial conditions.
