York S1-024-34680-000 Pressure Switch N/O 0.70/1.00/0.40"-WC

The York S1-024-34680-000 is a pressure switch that is used to measure the pressure of air in HVAC systems and turn on/off or modulate accordingly as per the pressure value set. It is normally open (NO) and only closes when the said pressure thresholds are reached. This part is designed to have a pressure of 0.70/1.00/0.40 of the water column to control air pressure for the efficiency of the system. This pressure switch is used in most HVAC systems for instance air handlers or furnaces, as it enhances the comfort, safety, and efficiency of the systems. It safeguards equipment from the impacts of over or under-pressure since pressure variations are well-measured. Further, since it does not cycle the system inappropriately it is also helpful in conserving energy.
