Snap Action Switches

Nason uses only the highest quality snap action electrical switches which insure a positive, instantaneous electrical contact under all operating conditions.

Diaphragms

Nason pressure switches incorporate elastomeric diaphragms to provide a positive media seal. Nitrile is the material of choice for most applications; ethylene propylene, fluorocarbon, fluorosilicon, and neoprene are readily available for specific applications.
