Description
The York S1-024-39490-000 Pressure Switch On Rise 0.26” WC is an essential part to be used in HVAC systems, which is meant to monitor the airflow in the ducts. This pressure switch is a delicate one that turns on whenever there is an increase in pressure within the duct and works normally when the system is in operation. The switch is designed on a basic concept that it has a diaphragm that changes its position depending on the pressure of the air. When the pressure inside the duct rises to the programmed level, the diaphragm bends and makes the electrical contacts of the switch.
