The invention concerns a snap-in locking device for a multistage rotary switch with a switch spindle that is connectable with a rotary knob, by means of which a switch part is adjustable into several switch positions, wherein the switch positions are determined by the pre-defined snap-in positions of the snap-in locking device, which comprises a snap-in lock element and counter-snap-in elements. If the invention provides that that the switch spindle is connected torque proof with an axle part that is snapped into an inner receptacle of a built-in switch panel part, that the axle part rests on the switch panel part and is lock-in adjustable between snap-in receptacles with cams that are each limited by two radially-aligned connector links, that the snap-in receptacles cover the entire circumference of the inner receptacle of the switch panel part, that the axle part can be set into rotary motion with the switch spindle by means of a rotary knob, which is attachable to the switch spindle, and that modifiable limit stops define the number of switch positions, then a snap-in locking device for a operating unit is created with simple and cost-effective production and assembly parts that is coupleable with other components of the operating unit and can be equipped with an over-rotation safeguard. <IMAGE> |
