<p>An operating device for electronic functional equipment, optionally in interaction with a display unit, where the device has a control element that is depressible for activation of a switch function, and stepwise is either longitudinally movable or rotatable in relation to the operating device housing, the movement of the control element preferably being indicatable, and where the device has means for detecting the stepwise movement of the control element. On each side of the movement path of the control element thereis respectively provided a first and second switch, depressible in the z direction. In connection with the control element there is provided a third switch, the control element being adapted to be depressible for activation of the third switch. Said first, second and third switches are interrelated to provide three possible options in the x direction for respective stepwise position of the control element in the y direction.</p> |
