An implantable magnet that can freely turn in response to an external magnetic field, thus avoiding torque and demagnetization on the implantable magnet. The implantable magnet can be combined with an electric switching function depending on the orientation of an external magnetic field, thus protecting an implanted coil and / or implant electronics against induction of over-voltage or performing an electric switching function for other various purposes. The magnetic switch may further include, for example, a first switching contact and a second switching contact. A magnetically soft body that includes an electrically conductive surface is shiftable between a first position where the body is in simultaneous contact with the first and second switching contacts, and a second position where the body is out of contact with at least one of the first and second switching contacts. The body and the implantable magnet are positioned such that the body is shifted to one of the first position and the second position as a function of the external magnetic field resulting in a magnetic force between the magnet and the magnetically soft body.

L'invention concerne un aimant implantable tournant librement en réponse à un champ magnétique externe, supprimant le couple et la démagnétisation sur cet aimant, lequel peut être combiné avec une fonction de commutation électrique selon l'orientation d'un champ magnétique externe, afin de protéger une bobine et/ou de l'électronique implantées contre l'induction de surtension, ou pour assurer la commutation électrique, ou bien encore pour diverses fonctions. Le commutateur magnétique peut aussi comprendre, par exemple, un premier contact de commutation et un second contact de commutation. Un corps magnétique mou à surface conductrice peut être déplacé entre une première position de contact simultané entre le corps et les deux contacts en question, et une seconde position sans contact. Le corps et l'aimant implantable sont positionnés de sorte que le corps passe à l'une ou l'autre des positions considérées, selon le champ magnétique externe produisant une force magnétique entre l'aimant et le corps magnétique mou.
