OPERATOR CONTROL DEVICE AND OPERATING METHOD

摘要

An operator control device for functional adjustment of a functional device includes an operator control knob which has an off position in which the operator control device is deactivated. Said knob can be brought into a working position for functional adjustment purposes. The working position is predetermined by a lock-in position, and, starting from the working position, the operator control knob can be pulled out of the operator control device or pressed into the operator control device against a counterforce which increases as the distance from the working position increases. Here, the operator control device includes a movement detection means for detecting movement of the operator control knob out of the working position in one direction or in the other direction. The movement detection means is connected to a controller of the operator control device so as to carry out functional adjustment in a manner dependent on the detected movement.
