Dwyer Instruments 1640-0 Switch 323613-751 facilitating the exact pressure dropThe Dwyer Instruments 1640 0 Switch is a high precision differential pressure switch engineered for specialized HVACR applications requiring floating contact null switch logic. Unlike standard snap acting switches, the 1640 series utilizes a single pole double throw (SPDT) floating contact design to provide two distinct actuation pointshigh and lowwith a defined "null" zone in between. This makes it an ideal solution for motorized damper control and
