Operating device for an electric device and operating method

摘要

The device (11) has a control unit (14) positioned on a support (12) in a movable and removable manner, and a contactless signal coupling provided between signal generators (19) and sensor surfaces (22), where the set of the sensor surfaces are provided as the generators. The sensor surfaces are coupled to contact surfaces (24), which are contactable or operable by an operator for a control function that is detected by the coupling at the generators. The generators and the sensor surfaces are arranged along corresponding concentric circles on the support and the control unit. An independent claim is also included for a method for operating a control device.
