High Pressure Switches

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.


CD high pressure pneumatic switches feature eight adjustment ranges from 10-7500 PSI and can be configured to be even more environmentally safe. These field-adjustable pressure switches have a set point tolerance of ±5 PSI or 5%.


The factory-set CF high pressure switch features set point ranges from 10-7500 PSI, with hardened steel pistons designed to provide longer life cycles in the most extreme applications and conditions.


The compact WX high pressure switch features a maximum operating pressure of 5000 PSI. The adjustable pressure switch has five ranges from 50-5000 PSI.


The factory-set XM high pressure switch features a maximum operating pressure of 5000 PSI, with set points from 40-4000 PSI.
