Pressure Vacuum Temperature Vintage

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. Our pressure switches utilize a long-life elastomer diaphragm that engages a snap action switch for consistent and accurate operation. Our high pressure models use a proven sealed piston sensor to withstand the highest pressures. Models are available for both pneumatic and hydraulic applications.

Our elastomer diaphragm and pistons move a precise .040 of an inch to ensure accurate instantaneous contact under all types of operating conditions. While nitrile is preferred for general use for diaphragms, we can also provide ethylene, propylene, fluorocarbon, fluosilicon and neoprene depending on what fluid you are using. Nason test every switch for accuracy prior to shipment.

Under most operating conditions, Nason switches have a service life of over one million cycles. Smart design, quality components and careful assembly make a switch that easily outlasts the competition.

We offer adjustable and factory preset models that are customizable for you design. We offer media connections in NPT, SAE and BSPP, as well as numerous electrical connections for any application.
