摘要

The control device (10) has at least one operating element (1) for selecting at least one function of the controller and/or a function of an external device, especially an electronic device. The at least one operating element is in the form of a toroidal section that is connected to the controller. The toroidal section is rotatable about a rotation axis (B) and/or displaceable. An independent claim is also included for the following: (a) a control system with an inventive control device.
