Description
The York S1-02435979000 Air Pressure Switch is an essential part used to monitor air flow pressure and control circuit operation based on pressure drop conditions in HVAC systems. It operates as a vital safety component in systems to regulate conditions by allowing system startup only when proper airflow is detected. It is closed on a pressure fall of 0.15″ water column, supporting safe furnace operation. It is applied in gas furnaces and air-handling equipment where systems regulate conditions and is designed to integrate with control circuits during typical installation and maintenance activities.
