1.59 in WC SPST Pressure Switch, 1/4 in Barb
SKUSWT3570
Description
The Trane® SWT3570 is a single-pole, single-throw (SPST) pressure switch set at 1.59 inches of water column (WC), built for OEM HVAC replacement. A 1/4-inch barbed connection ties it into the sensing line, and the switch opens or closes one circuit when pressure reaches its trip point. Trane specifies it to confirm proper draft or airflow before the system continues its firing sequence. It drops in as a direct replacement to keep pressure-proving accurate in Trane furnaces and air handlers.$125.59
