Key Features
- Genuine OEM Part – Manufactured by York to match original system specifications for reliable, long-term performance.
- Air / Pressure Switch Functionality – Monitors air pressure (or vacuum) in HVAC systems to help verify correct airflow before allowing system operation.
- SPNO (Single Pole, Normally Open) Contact Configuration – Switch is “normally open,” closing when pressure drops to trigger system response.
