Trane SWT0838 SPST Pressure Switch 1.08" WC

The Trane SWT0838 is a pressure switch that is a Single Pole Single Throw (SPST) pressure switch used in Trane HVACs. Cubic (4.2”х 2.4” х 0.7”), is a compact device that plays a major role in ensuring the safe and efficient operation of the unit. There is a pressure rating of 1.08WC, and this simply means that it acts more like an off-on type switch. Maintaining one particular set point of pressure, normally near 1.08 inch of WC, the switch energizes or de-energizes the circuit as per its connection type. This switching capability is critical for managing diverse HVAC components, comprising turning off the furnaces once the air pressure drops below the safe limit towards overheating.
