Abstract

Cet actionneur magnétique comporte une partie magnétique fixe (3) qui coopère magnétiquement avec une partie magnétique mobile (1) et des moyens (4) pour déclencher le déplacement de la partie magnétique mobile (1). La partie magnétique mobile (1) comporte au moins un aimant (1-1) et la partie magnétique fixe (3) présente au moins deux zones d'attraction (3-2) sur lesquelles la partie magnétique mobile est susceptible de venir se coller. La partie magnétique mobile (1) est en lévitation lorsqu'elle n'est pas collée sur l'une des zones d'attraction (3-2) son déplacement se faisant par guidage magnétique.
