摘要： An apparatus for grinding coffee is described. The apparatus includes a mechanical user input device, 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 the mechanical coupling of the user input device to the grinding unit. The user input device provides electrical power to the grinding unit when it is displaced from an initial position and ceases the provision of electrical power to the grinding unit when it is in the initial position. The mechanical coupling returns the user input device to the initial position when the grinding unit is operational.
