SOR Pressure Switch

Depending on the installed application, pressure switches may be required to contain an explosion of a specified gas, vapor or dust which may occur within it. Other requirements may be to isolate the switching mechanism from the elements and corrosive environments or atmospheres or be weathertight for external use. SOR switches are engineered to exceed the minimums of the required agency approval standards.
