Control assembly for e.g. vehicle battery circuit opening and closing device, has frame closed by case with stops, in cooperation with pin, tending to push and bring end teeth between worm coils, when motor is fed and not fed, respectively

摘要

The assembly has a frame in which a motor is housed on an output shaft. A worm (12) driving a toothed wheel (32) is wedged on the shaft. The frame is closed by a case with elastic stops (46, 47). The stops (47, 46) in cooperation with a pin (41) tend to push and bring end teeth between worm coils, when the motor is fed and not fed, respectively, such that the motor continues to freely rotate by inertia, when the teeth leaves the worm.
