Abstract: In known rotary knobs, an intermediate part and a universal joint are arranged between a base member and a switching handle that can be connected thereto for compensating position deviations between the longitudinal axes of the base member of the rotary knob and of an actuation shaft of a control device or the like. The new rotary knob can be manufactured and mounted in a simplified manner and can satisfactorily compensate for position deviations. The switching handle can be connected to the base member essentially so as to be locked against rotation and the base member has a bearing part with snapping means for a connection with a housing part. The rotary knob can be used, for example, on front sides or operating desks of domestic apparatuses or for operating program control devices.
