At Nason, our vacuum pressure switches feature a “no-creep” design with a snap-action electrical device activated by an elastomer diaphragm or piston. Available in factory preset or adjustable vacuum switch models, these components maintain their contacts in either an open or closed state until a precise pressure set point is reached. At that point, they snap over center to a new state and will remain there until the pressure drops below the exact set point. At that point, the vacuum switches will snap back to their original state.
Tested for 100% accuracy, the snap action design ensures components change state at their precise set points every time without “creeping”.
We offer both factory preset and adjustable vacuum pressure switches ranging from 1″ to 29″ of mercury (Hg).
These durable vacuum switches are NEMA 4 & 13 rated with an operational life exceeding one million cycles under most conditions.
Choose from a wide variety of configurations and electrical connection options to tailor your vacuum switches to your application.
