    • Electronic appliances can seem complicated to operate due to the large number of operating buttons. The aim of the invention is make the operation of an electronic appliance clearer whilst maintaining a high level of user comfort. To this end, an operating element for electronic appliances with a display, especially car radios, is provided with an incremental encoder (3) which can be activated in two opposite directions, and a control mechanism (6) for converting the incremental impulses produced into a corresponding control signal for adjusting a setting of the electronic appliance. The incremental encoder (3) can be activated in a third direction to select another setting. The invention is characterised in that when the incremental encoder (3) is activated in the third direction, the control mechanism is switched over so that a plurality of settings displayed on the display (2) can be selected in succession by means of the incremental impulses of the incremental encoder when it is activated in one of the two opposite directions. By switching the control mechanism (6) back, it is possible to adjust the value of the setting through the incremental impulses.
