Cleveland Controls NS2-1068-01 Pressure Switch 328140-751 ECMs use internal electronics toThe Cleveland Controls NS2 1068 01 Pressure Switch is a critical OEM replacement engineered for precise atmospheric monitoring in high demand HVAC systems, industrial air handlers, and furnace draft inducer circuits. Factory calibrated to a fixed set point of 0. 20" w. c. (Water Column), this differential air pressure switch ensures the blower motor is moving sufficient air to safely vent combustion gases or maintain required static pressures.
