4 About This Product

4.1 Product description

The pressure switch is used to open or close an electrical contact when a preset
pressure value is reached.

4.2 Performance specifications

An appropriate medium is applied to the pressure switch at the G1/4 connection
or on the flange. A diaphragm actuates a microswitch (change-over switch) via a
mechanism once the preset switching pressure is reached.
