Description
The York S1-024-35324-000 is an OEM replacement pressure switch engineered for use in York heating systems and compatible furnace applications. This Single Pole Normally Open (SPNO) pressure switch is designed to close on a fall in pressure, providing critical safety and operational control within the inducer and combustion air proving circuit.
Product Overview
This pressure switch monitors negative pressure (draft) produced by the inducer blower assembly. When pressure drops to the designated setpoint, the normally open contacts close to signal the control board that proper draft conditions are established — a fundamental safety interlock in modern gas furnace design. The dual setpoint rating of 0.6″ / 0.2″ W.C. ensures precise, reliable switching across the required operating range.
