York S1-024-34560-000 Pressure Switch 0.4"/0.8" WC

The York S1-024-34560-000 pressure switch is an essential element of HVAC systems that controls the flow of air by measuring pressure in the ducts. This device functions by switching electrical circuits ‘on’ or ‘off’ depending on two set pressure levels, thus achieving the performance. The pressure switch is built from brass or stainless steel to withstand the load in HVAC systems. It has a pressure range of 0.4 to 0.8 inch W.C., which enables it to sense small changes in pressure and enable precise control of the fan and damper, as well as other systems.
