SWITZER offers a very economical and comprehensive range of Industrial Pressure & Differential Pressure Switches specially designed for a wide  range of OEM applications  such  as  oil,  water,  steam,  gas  or  air pressure controls. The  sensing element and switching  components are the same time-proven quality elements available in Switzer mainstream product ranges.

The pressure changes sensed by the bellows assembly actuates a snap acting microswitch at desired pressure setting. The cut-in and cut-out points are adjustable over the entire range.

The differential pressure model is ideal for control of pressure difference between high and low pressure points such as filters, boilers etc.

The potential free contact can be used for alarm annunciation, control, interlock or direct start-stop of industrial equipments.

Complementary, pressure and differential pressure switches with Stainless Steel sensing elements and wetted parts are available for aggressive process media in Classic, Sovereign and Prince Series.
