Details: HR-021**1

Function

The membrane switch (changeover) in the terminal box switches , when a hydrostatic pressure of 15 mbar caused by the rising liquid rises up. The switch falls back with a pressure drop of 6 mbar.

The switching points are factory-set and fixed.

This device may be used with any cicuit, if this circuit complies with the connection values of the switching element.
