York S1-024-35324-000 Pressure Switch Els PW 17895 protecting the heat exchanger fromThe York S1 024 35324 000 Pressure Switch is a critical safety component engineered for two stage gas furnaces and air handlers. This dual air pressure switch features a precision calibrated 0. 60 0. 20 inch WC setpoint, operating on a Close on Fall logic to ensure the inducer motor maintains the necessary vacuum for safe combustion and venting. As an SPNO (Single Pole Normally Open) device, it monitors the differential pressure across the heat
