Trane SWT1211 Switch R-410A where maintaining a positive sealThe Trane SWT1211 (also categorized under SWT01211) is an essential high pressure cutout switch designed for HVAC system protection. This SPST cutout switch features a single pole single throw configuration, calibrated with a 300 405# pressure range. In the field, this means the switch is engineered to interrupt the electrical circuit (cut out) when system pressure reaches 405 PSI and reset (cut in) at 300 PSI, effectively preventing compressor damage
