Description
The York S1-02427659001 Air Pressure Switch is an essential tool required in the regulation of airflow in different HVAC systems. It is designed to work within a pressure range of 0.35”-0.90” WC and has the Normally Open contact arrangement. This means that the switch is open at normal condition and it is closed when the air pressure is equal to a set value within the range. This mechanism enables the switch to sense changes in the airflow and cause a response from the HVAC system. When the pressure gets low than the lower set point, the switch turns on and signals the HVAC system to adjust the flow of the air.
