Pressure Switches

Pressure switches can be used to automatically monitor pressure levels in a pneumatic system, or be used for more complex monitoring functions in air, water, hydraulic or any neutral fluid applications.

Norgren and Herion have a huge range of pressure switches from our simple, strong mechanical switches - our 18D is one of the most recognisable switches of its type in the industry - to our 33D offering off-line programming, digital or analogue outputs and pressure windows are only some of its great features.
