Description
The Daikin-McQuay 151107J High Pressure Switch is a control part that continuously monitors refrigerant discharge conditions and interrupts system operation when unsafe limits are reached. It operates through a pressure-actuated mechanism that triggers an electrical cutoff when pressure rises beyond the set threshold, stopping compressor operation to prevent equipment damage. In HVAC systems, it is used in air conditioning, heat pumps, and cooling units to maintain safe operating limits and system stability. connected to the high-pressure side of the circuit and supports equipment protection, operational safety, and reliability.
