1Overview of pressure switch type DG
Pressure switches open and close an electrical contact at a previously dened
pressure. As soon as the pressure is reached, a further work step is started or
stopped by an electrical signal.
Features an benets:
■Compact design
■Option of integration into the HAWE modular system
■Operating pressures up to 1000 bar
Inten e applications:
■General hydraulic systems
■Machine tools
