Patent ID: 8376253

Claim:
A method of operating a food processor comprising: i. providing a food processor, the food processor comprising: a coupling point to attach processing devices to the food processor; a detection device disposed at the coupling point and comprising a first actuating region, and a second actuating region that is oriented differently from the first actuating region; and a contact switch in proximity of the detection device; and ii. attaching to the coupling point either a first processing device or a second processing device, wherein: the first processing device comprises a first actuating element to attach to the coupling point in a first configuration characterized by actuation of the first actuating region by the first actuation element; the second processing device comprises a lid, and a second actuation element to attach to the coupling point in a second configuration characterized by actuation of the second actuation region by the second actuation element; and the detection device and the contact switch are configured such that the contact switch is toggled by the detection device upon actuation of either of the first activation region or the second actuation region.
