Dwyer 1640 Series Floating Contact Null Switches for High and Low Actuation-

Dwyer 1640 Series Floating Contact Null Switches for High and Low Actuation

The 1640 is equipped with a single pole, double throw floating contact switch (not snap acting) so it functions as a null switch. As the diaphragm moves in response to pressure changes, it moves the floating contact to cause switching action at two preset points with no switching action between these points.
