1Overview of pressure switch type DG

Pressure switches open and close an electrical contact at a previously dened

pressure. As soon as the pressure is reached, a further work step is started or

stopped by an electrical signal.

Features an benets:

■Compact design

■Option of integration into the HAWE modular system

■Operating pressures up to 1000 bar

Inten e applications:

■General hydraulic systems

■Machine tools
