ABSTRACT:
A low-energy, long-life, magnetic latching apparatus includes a permanent magnet, an electro-magnet and a bi-stable armature. The magnetization axes of the permanent magnet and the electromagnet are substantially parallel to maximize respective flux coupling. Back-iron is located immediately adjacent the permanent magnet opposite the electro-magnet such that the permanent magnet is intermediate the back-iron and electro-magnet. The armature is arranged to minimize any air-gap between the armature and permanent magnet occasioned by the pivotal movement thereof. The back-iron provides for an increased permanent magnet working point and parallel flux path for electro-magnetic flux.
