Vacuum Switches, Vacuum Pressure Switches and Adjustable Vacuum Switches from Neo-Dyn.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 synochronized 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 cycle life.
