BISTABLE MAGNETIC FASTENING DEVICE

摘要

The invention relates to a bistable magnetic fastening device that comprises: a non-magnetic bearing housing (250) in the form of a duct having a rectangular cross-section; a magnetic circuit including a base and three pins perpendicular to said base (222), the two outer pins (230) and the base (222) defining a U; a permanent magnet (213) in the form of a rod provided between the base (222) and the central pin (275); a coil (214) surrounding the central pin (275); a mobile planar part (221); return and guiding means connected to the inner side walls of the bearing in order to return the magnetic circuit towards the upper portion of the bearing housing.
