Description
The Trane SWT1719 High Pressure Switch is a refrigerant pressure monitoring control designed to supervise high-side system pressure conditions during cooling operation. It is configured to open the electrical circuit at 405 PSI and reclose at 300 PSI, allowing controlled response to elevated refrigerant pressure levels and supporting compressor protection during operating cycles in HVAC systems. The switch is installed in compatible compressors or refrigerant line assemblies during servicing or replacement procedures, where it interfaces with the pressure control circuit and safety controls. It operates as a protective pressure control component that assists with system safety, pressure regulation.
