摘要

The device (2) has two float-controlled switches (7,8) arranged in the container, which interrupt filling at defined level in the container. Both switches are controlled by a single float (5), which closes the former switch in a lower minimum position (I) and opens in an upper maximum position (II) of the filling level. The single float holds the other switch closed in the lower minimum position and opened in the upper maximum position. The former switch is designed as a shutter in its function and the latter switch is designed as an opener in its function.
