ABSTRACT:
The device comprises at least one lead screw (2) driving a sliding yoke (23) whose guide bar (22) is mounted on a rocker arm (19). The lead screw actuates a switch (27) by means of a cam (28) via the sliding yoke. A deliberate action on the rocker arm moves away the sliding yoke (23) which is brought instantaneously into initial position by a spring (25). The lead screw (2) is for preference disengageable by means of an arm (29) driven by the axle of the sliding yoke. This arm provides an angular positioning of the lead screw by acting on a heart-shaped cam (10).
The device permits rapid, sure and precise setting of the stopping points of a motor.
