摘要

The actuator has a carriage (8) which is connected to the lever to be shifted. Supply of current to the motor (11) rotates a ramp carrying element (7) and this shifts the carriage (8) by action of helical ramps (18) on pins (29) carried by the carriage. A device comprising a cam (20) and switch (10) interrupts the supply of current to the motor at the end of a quarter of a rotation of the element (7) and the pins (29) are then disposed between two successive ramps (18). The carriage can be shifted without obstacle with small effort by a manual action on the lever. The actuator may be used for the simultaneous locking or unlocking of all the locks of an automobile.
