Main markets • Chemical- and Petro-Chemical Industry • Oil Gas On- and Off Shore • Power Plants • Machine and OEM market • Construction and Engineering Definition of a Pressure Switch  Switches that detect a certain amount of force and activate electrical contacts when the pre-set force is reached  A switch that is actuated by a change in pressure of a gas or liquid  A switch used to turn an electrical device on or off when a specified fluid pressure is reached.  A pressure switch measures pressure, typically of gasses or liquids. Pressure is an extension of the force required to stop a fluid from expanding and is usually stated in terms if force per unit area.  A pressure switch usually acts as a transducer : it generates a signal as a function of the pressure imposed.  Pressure switches are devices that are configured to sense a change in pressure and respond in a specified manner.  A pr
