Abstract
An operating device having a rotatable crank drive which can be actuated by repeatedly pressing and releasing a knob or push-button. The push-button is thus alternately fixed in an operating position, i.e. the out position, and a locking position, i.e. the pressed-in position. A rotatable locking ring which can be axially displaced in an elastic manner and the body of the operating device include crank or link elements which are alternately distributed around the circumference, and in which the knob or push-button can be securely locked in a precise position.

An operating device for a flush operating knob that is axially locked and unlocked under spring load, for a rotary switch of an automobile, comprising:
- a multiple toothed, circumferential link drive, in which a body of the operating device, and a locking ring that is axially fixed and pivoted on the operating knob have successively arranged, circumferentially distributed link elements in which the operating knob is axially lockable.
An operating device for a rotary switch with a flush operating knob that is extendable under spring load, comprising:
- a body having a plurality of fixed link elements circumferentially distributed on an inner surface thereof;
- and
- a locking ring fitting within said body and being axially fixed and pivoted on said operating knob, said locking ring having successively arranged, circumferentially distributed movable link elements thereon that cooperate with said fixed link elements to form a multiple toothed circumferential link drive for axially locking and unlocking said operating knob.
