Description
The York S1-024-39479-000 Pressure Switch is a control equipment used to monitor the air or fluid pressure and open or close its contacts once the temperature has reached 0.33″ of water column in HVAC systems. It operates by a diaphragm or sensing element that reacts to tiny variations in pressure, allowing the switch to operate accurately in range. It is mounted in ductwork, fan or blower circuits and regulates the appropriate airflow and balance of the system.
