Description
Ensure safe and reliable airflow and vent-pressure monitoring in your HVAC system with the genuine YORK S1-024-35311-000 pressure switch. Designed to detect proper negative pressure (vacuum) — as generated by the inducer/blower motor — this essential switch helps verify that exhaust and venting are functioning correctly before the furnace ignites.
Key Features
- –0.65″ W.C. (Water Column) trigger threshold — monitors negative pressure and closes when proper vacuum is established, ensuring safe combustion venting and preventing operation under unsafe vent-pressure conditions.
- SPST (Single-Pole, Single-Throw) switch — simple, reliable on/off contact for controlling ignition or burner circuits based on pressure/vacuum status.
- OEM-grade part from YORK — assures correct specifications and compatibility with YORK (and many compatible) HVAC furnaces and air-handlers that require this style of pressure-sensing switch.
- Compact and easy to install — small form factor, convenient 1/4″ barbed (or NPT) vacuum port for hose hookup, and straightforward electrical wiring make it a direct replacement for original units.
- Critical safety and performance role — helps ensure the inducer motor is creating sufficient draft before ignition, reducing the risk of improper combustion, carbon monoxide, or vent-blocking hazards.
