Pneumatic, Temperature & Pressure Switches

Unlike competitors’ switches, that “creep” between on and off, Nason pressure switches, pneumatic switches, and temperature switches are built for reliable positioning. Made in the USA, these compact and customizable switches feature a snap-action device, which makes their design more precise and repeatable. Their elastomer diaphragms or pistons move a precise .040 of an inch to ensure accurate, instantaneous contact under all operating conditions.

Our pneumatic, temperature and pressure switches are UL, CSA, and military approved with an operational life of over one million cycles and a large variety of electrical connections. Need a switch with specs you don’t see? Just ask us. We’ll be happy to custom build it for you.
