Pressure Switches

Hydraulic and Pneumatic Pressure Switches

Nason’s complete line of pressure switches offers design engineers a choice of low to high pressure switch models ranging from 2 PSI to 7500 PSI. Models are available for both pneumatic and hydraulic applications. All of Nason’s pressure switches use a snap-action electrical device activated by a precise, long-life elastomer diaphragm or piston offering a precise and repeatable design.

The snap-action design will maintain its state with contacts either open or closed, until a precise set point is reached when it will snap over center to a new state. It will remain in that state until a distinct change towards its original setting is sensed, at which time it will snap back to its original state. The design’s snap action feature prevents contact intermittency near its switch point, which is common in creepers.

As system pressures fluctuate, our switches inherent differential prevents searching. Nason uses only the highest quality snap action switches. These switches and Nason’s are UL, CSA, and military approved.
