Trane SWT03114 Dual Pressure Switch

The Trane SWT03114 Dual Pressure Switch is a component that detects and reacts to air pressure variation in blower and inducer loops applied in HVAC systems. It has two pressure-sensing components that sense high and low conditions and transmit the same signals to the system control to allow normal operation or a shutdown in case of unsafe conditions. Placed in residential furnaces, light commercial furnaces, and air handlers, it is fitted in the pressure tubing system between the blowers.
