Trane SWT2515 Pressure Switch Els PW 17895 As a critical component inThe Trane SWT2515 is a high precision HVAC pressure switch calibrated to a 1. 36" WC setpoint for critical safety monitoring in gas furnaces and air handlers. This SPST (Single Pole Single Throw) air pressure sensor acts as a primary safety interlock, ensuring the draft inducer motor generates sufficient negative pressure before the ignition sequence begins. Designed for maximum reliability in high cycle environments, the SWT2515 provides a 1 4" barb
