ABSTRACT:
A control device for a valve (8) in the water supply conduit (7) of a reservoir (1), e.g. the water reservoir of a coffee machine, comprising a diaphragm (10) disposed in a reservoir wall and having an operating stud (11) for a tilting member (12, 40) swivelling between two end positions, the tilting member being associated with a bistable switch. The tilting member (12, 40) is retained in one, first end position by magnetic force (15), and is then in the path of motion of the operating stud (11). The swivelling movement of the tilting member (12, 40) to the other, second end position is used for operating a microswitch (18) incorporated in the control circuit of the valve (8).
