High pressure switches for pneumatic and hydraulic applications

All of Nason’s electronic pressure switches feature a “no-creep” design with a snap-action electrical device activated by an elastomer diaphragm or piston. These high-pressure switches keep their contacts either open or closed until a precise set point is reached. At that point, they snap over center to a new state and remain there until pressure distinctly lowers, triggering the pneumatic switches to snap back to their original state.

We offer both factory preset and adjustable pressure switches, with an operational life of over one million cycles under most operating conditions. Our UL-, CSA-, and military-approved switches offer a wide variety of electrical connection options and are fully customizable.
