York S1-02434561000 Pressure Switch 0.95" WC 0.4" WC

The York S1-02434561000 Pressure Switch is an essential component in HVAC systems that is used to measure the pressure differences within the HVAC system. Based on the differential pressure sensing technology, it effectively measures the pressure is difference between two points in the HVAC equipment. When the pressure differential goes to a certain set point 0.95”WC in this case the switch initiates an action for example turn on or off a fan, pump or system. This kind of control also helps to maintain higher system efficiency by suppressing problems, such as excessive flow resistance, dirty filters or failed dampers.
