York S1-024-35264-000 Pressure Switch 1.6" WC SPNO Close On Fall

The York S1-024-35264-000 Pressure Switch is designed to detect pressure levels in order to maintain safety and efficiency of HVAC systems. This circuit has a pressure setting of 1.6 inches WC, and it is designed to close any time the pressure is below this setting.Its SPNO (Single Pole, Normally Open) design means that components are switched on or off depending on the pressure drop to guarantee that the system reacts to low pressure conditions.Air conditioning units, heating systems, and ventilation systems require pressure control to protect from low pressure conditions.
