ASCO SA32DW Tri-Point Differential Pressure Switch is a member of ASCO’s S-Series differential switches and uses a tri-point configuration to translate differential pressure into an electrical switch action. It carries an electrical rating of 125–250 V AC and up to 20 A, enabling direct interfacing with standard control circuits. In S-Series design, the switch unit and transducer form a compact two‑component assembly, making it suitable for HVAC, filtration, and dust‑collection applications where control or alarms are triggered by pressure differences.
