ABSTRACT:
The invention concerns an electromagnetic lock comprising two parts, one of which comprises an electromagnet and the other a mobile armature capable of moving to counter the return springs when the electromagnet is energized. One of the parts has at least one protuberance extending from one edge of the corresponding part to the proximity of the other edge, the protuberance sized and positioned to be capable of penetrating into a housing of the other part when the parts coincide and the electromagnet is energized, the height of the protuberance being less than the distance normally separating the two parts when the electromagnet is not energized. This abstract is neither intended to define the invention disclosed in this specification nor intended to limit the scope of the invention in any way.
