Trane SWT3971 Pressure Switch R-134A Its compact design allows forThe Trane SWT3971 Pressure Switch is an essential safety component engineered for induction monitoring in high efficiency Trane and American Standard furnaces. This SPST pressure switch (Single Pole Single Throw) is factory calibrated at a 1. 00" W. C. set point to ensure the inducer motor maintains the precise vacuum required for safe combustion and flue gas venting. As a 28VA pilot duty component, the SWT03971 effectively prevents the ignition cycle
