Differential Switches, Differential Pressure Switches and Pressure Differential
A negative rate type pressure switch (i.e., a Belleville spring) is a snap acting
device. At a certain pressure (apex of the spring curve) the spring snaps over center.
At this point, it takes pressure (force) to continue its movement. The pressure
switch set point is a function of the Belleville spring. The electrical switch is
in a fixed position and is synchronized to the movement of the Belleville. Our Neo-Dyn
switches feature a negative rate Belleville spring snap acting device which offers
greater set point stability, vibration resistance, over-pressure capability and
