摘要： An actuator including a device for providing a magnetic field including a magnetic field generator, the actuator further including an output element being moveable between a first position where it blocks or breaks an associated mechanical transmission path and a second position where it unblocks or forms part of an associated mechanical transmission path, the output element being moveable as a result of changes in its local magnetic field as generated by the magnetic field generator, at least a part of the device being moveable to change said local magnetic field to effect movement of the output element.
