Abstract
An operating control unit for an electrical appliance with an operating field is mounted on an underside of the operating field. The operating control unit includes a frame body, a flat component carrier being mounted to the frame body from behind and having piezo-active sensor elements, and a back support mounted to a back side of the frame body and enclosing the component carrier. The operating control unit has after pre-assembly two different assembly states. In a pre-mount state the back support is fixed to the frame body enclosing the component support, and some locking means of the frame body are formed as pre-mount locking means and are holding the back support against disassembly. In a final-assembly state the back support is pressed against the frame body with less distance between the two, and final-assembly locking means of the frame body are holding the back support in a closer position than the pre-mount locking means.
