摘要
An actuation device which includes a holding magnet, an attracting magnet and an armature therebetween, both magnets being excitable by the same electromagnetic source. The armature comprises two half portions interconnected by a non-magnetic plate and operating such that upon saturation of the holding magnet with current, the armature will be disengaged by the holding magnet and drawn towards the attracting magnet.
