Mercoid DPA-43-804-62E Differential Pressure Switch is a differential pressure sensing device from Mercoid that detects the difference between two pressure points and translates it into an electrical switch action. When the sensed differential pressure crosses its operating threshold, the switch energizes or de-energizes a circuit to provide a clear control signal in systems that monitor pressure changes. Model DPA-43-804-62E specifies this exact Mercoid part within the differential pressure switch lineup.
