摘要： A kitchen appliance has a power switch for controlling supply of power to a motor and a separate control circuit (18) for controlling the speed. A button (14) for control by the user is provided for controlling both the actuation and speed. A carrier (40) carries the button, and also carries a first actuator (44, 86) for mechanically actuating the power switch when the button is first moved. When the button is further moved, the motor speed is controlled.

摘要： An apparatus includes a first fuse having a first breaking capacity, a first set of time-current characteristics, and a first rating; a second fuse having a second breaking capacity, a second set of time-current characteristics, and a second rating. The second set of time-current characteristics is different from the first set of time-current characteristics and the second rating is different from the first rating. The first fuse and the second fuse are connected in series, the value of the first breaking capacity is set such that at a high current fault condition the first fuse acts to interrupt the current before the second fuse, and the value of the second set of time-current characteristics is set such that at a locked rotor condition of the motor unit the second fuse acts to interrupt the current before the motor unit reaches a maximum winding temperature.
