Abstract
The invention relates to an operating device (1) with an adjustable lever (2) and a sensor mechanism (8), comprising a transmitter coil (5), which may be energized with an alternating current by means of an alternating current supply (7) and a receiver coil arrangement (9). According to the invention, such an operating device may be designed such as to be reliably useful even with intense interference with a construction as technically simple as possible without complex screening measures, wherein the frequency of the alternating current energizing the transmitter coil (5) and the pass frequency of a receiver filter (13) in the receiver coil arrangement (9) are synchronously changed according to a preset program by means of a control unit (14), such that, by means of the operating device (1) and the method carried out therewith, a change to a frequency which is interference or interference signal free can be continuously carried out.
