Claim 7:
8. A coffee machine, comprising:
an apparatus for grinding coffee, comprising:
a mechanical user input device, wherein the mechanical user input device comprises a plurality of positions, at least one of which being an initial position;
a grinding unit for grinding coffee;
an electrical switch which connects the grinding unit to a source of electrical power; and
a mechanical coupling for mechanically coupling the mechanical user input device to the grinding unit,
wherein the mechanical user input device is configured to:
close the electrical switch when the mechanical user input device is displaced from the initial position; and
open the electrical switch when the mechanical user input device is in the initial position, and

wherein transmission characteristics of the mechanical coupling are configured to return the mechanical user input device to the initial position when the grinding unit is operational, such that an amount of displacement by which the mechanical user input device is displaced from its initial position determines a number of rotations that the grinding unit performs, which in turn determines an amount of coffee to be ground;

a brewing chamber for receiving ground coffee from the grinding unit; and
a controller for controlling a brewing process of the coffee machine,
wherein the apparatus further comprises:
a detector for detecting when the grinding unit is operational and the controller is coupled to the detector.
