Dwyer's 1831 DPDT low differential pressure switches with manual reset eliminate common problems associated with typical high duct static cutout installations. Using an 1831 reduces both material and labor installation costs. Because the 1831 doesn't require power to drive its outputs, there's no need for a separate power loop or its associated

Our most popular Series 1900 Compact Low Differential Pressure Switch combines advanced design and precision construction to make these switches able to perform many of the tasks
