NS Pressure Switch

Clark Solutions
NS Pressure Switch
Set Point Range, 1.5-100 PSI

DESCRIPTION
Model NS is a simple, reliable low cost pressure switch that uses a spring loaded diaphragm as the sensing element. A Buna-N diaphragm is standard however a selection of other diaphragm materials are optionally available.
The switch point can be factory preset or field adjustable.

In operation, the diaphragm actuates a snap action electrical switch that insures a positive, instantaneous electrical contact under all operating conditions.
