Pressure switches are industrial components that convert pressure changes into an electrical signal. When the system pressure changes, the internal electrical switch either opens or closes.
Select »
Vacuum switches are industrial components that measure pressure variations less than ambient pressure which is used as a baseline reference point. When the system vacuum changes, the internal electrical switch either opens or closes.
Select »
Compound switches are capable of having either a pressure or vacuum set point. Excursions between pressure and vacuum will not damage the switch.
Select »
A differential pressure switch is an instrument that converts a differential pressure change between two systems to an electrical signal. When the pressure in one of the systems changes, the internal electrical switch either opens or closes.

Liquid Level switches are electromechanical devices that open or close an electrical circuit in response to a change in the level of a liquid in storage areas such as tanks, reservoirs, sumps and wells.
Select »
Temperature switches are electromechanical devices that open or close an internal electrical switch at a specific temperature. These can be used either in liquids, such as coolants and engine or hydraulic oils, or gases, such as air or nitrogen.
