A permanent magnet, bistable actuator mechanism (250) that uses magnetic repulsion for actuation, the actuator mechanism (250) having a first translator member (252) with a permanent magnet element (252) displaceable between a first position and a second position and a second translator member (254) having a permanent magnet element (254) displaceable between a first position and a second position with the permanent magnet elements (252, 254) in mutual repulsion, the translator elements (272) being arranged in a frame (260, 262, 266) or containment structure (256) that limits displacements of the first and second translator members (252, 254) with one of the translator members being a master member (252) and the other being a slave member (254), such that displacement of the master member (252) from one position to the other displaces the slave member (254) in an opposite direction with the displacement process being reversible.

L'invention se rapporte à un mécanisme actionneur bistable (250) à aimant permanent, qui utilise la répulsion magnétique pour actionner. Ce mécanisme actionneur (250) comporte un premier élément à translation (252) comprenant un élément à aimantation permanente (252) susceptible d'être déplacé entre une première position et une seconde position, et un second élément à translation (254) comprenant un élément à aimantation permanente (254) susceptible d'être déplacé entre une première position et une seconde position, lesdits éléments à aimantation permanente (252, 254) se repoussant mutuellement. Les éléments à translation (272) sont disposés dans un cadre (260, 262, 266) ou une structure de confinement (256) qui limite les déplacements de ces premier et second éléments à translation (252, 254), l'un desdits éléments à translation étant un élément maître (252) et l'autre étant un élément esclave (254), de sorte que le déplacement de l'élément maître (252) d'une position à l'autre déplace l'élément esclave (254) en sens opposé et de sorte que le processus de déplacement soit réversible.
