Description
The Trane SWT03277 SPST High Pressure Switch is aimed to monitor and regulate pressure conditions in compatible cooling and refrigeration equipment. Configured with 650 PSIG open and 500 PSIG close settings, this single-pole single-throw switch responds to pressure changes by controlling connected electrical operations during the process. Commonly installed in residential and commercial HVAC systems, it operates within the safety control assembly to help protect compressors and related components from excessive pressure levels. The switch supports stable equipment performance by interrupting or restoring circuit operation according to specified pressure thresholds.
