Trane SWT1106 SPST Pressure Switch Open 1.20" WC Close 1.45" WC

The Trane SWT1106 SPST is a single pole single-throw limit switch to be used in industrial HVAC applications. Limit switches are those switches that are employed to signify a position or status alter of a specific mechanism component. It is possible to incorporate this into an HVAC system in such a way that it can detect the status of a damper, for example, if the damper is open or closed: This will trigger something, for example, turning a heating element on or off or stopping a fan. Housed in a compact case and operating through the internal spring mechanism also alters its state according to the pressure applied.
