    Abstract: A method for positioning a switch in a speed limiting device, wherein, for a limit switch, which interrupts the controlling process of the speed limiting device consisting of an electronic control unit, an electromechanical servo unit and a mechanical clutch arrangement, a positioning method is utilized and in order to carry out this method, an arrangement is provided in which the limit switch is fastened on a slide which is displaceably supported with the servo component of the speed limiting device. Arranged in the slide, which, in addition, carries a switchover contact bank serving to actuate the switch, there are provided locking bars with which, together with catch paths constructed at a housing of the servo unit, an exact fixing of the slide can be achieved at the end of the positioning process by means of reversing the rotational direction of the servo motor.
