Trane SWT3324 Pressure Switch

Trane SWT3324 is a pressure switch, particularly for HVAC applications which stands for Heating Ventilation, and Air Conditioning. A compact device and has a length of 4.4 inches. Installation is also quite easy, due to the 1/4” x .032 quick-connect terminal – which is reliable nonetheless. The Trane works more like a safety switch in a way that it checks the pressure within the Trane HVAC system. It functions to detect changes in pressure – which subsequently turns on or off an electric circuit. When the pressure alarm has been reached a predetermined set point is established the switch operational sequences include turning on or off compressors, pumps, or fans.
