Description
The Johnson Controls P74JA-2 is a differential pressure switch that has been designed for HVAC use. This is because it has an SPDT switch type and can be used for a number of control duties in a pressure range of 8-60 PSI. It is strong and reliable for the commercial and industrial HVAC applications. This switch measures the differential pressure changes of the HVAC ducts or systems. The SPDT switch comes into operation and informs the HVAC system to make the required changes when the pressure is high or low from the set levels. It has a long service life and high accuracy to ensure the control of pressure conditions, reduce the damage of the system, and improve efficiency.
