Description
The Trane SWT01719 High Pressure Control Switch is a refrigerant safety control component designed to monitor and regulate high-side pressure conditions in HVAC systems. It operates by opening the electrical circuit at approximately 405 PSI and resetting, closing at around 300 PSI, helping protect the compressor and related components from excessive refrigerant pressure during operation. It is installed in compatible condensing units and refrigeration assemblies during servicing or replacement procedures, where it connects to the high-pressure line and control circuit to monitor system operating conditions. It operates as a protective pressure switch that supports compressor safety, system reliability.
