Abstract

L'invention concerne un interrupteur magnétique (10), qui permet de détecter un mouvement relatif entre une première et une seconde structures adjacentes (14, 18) et d'empêcher toute tentative de manipulation magnétique de l'agencement (10). L'agencement (10) comporte une paire d'éléments d'interrupteur adjacents et superposés (22, 24), l'un supérieur et l'autre inférieur, conçus pour être montés sur la première structure (14). L'élément d'interrupteur inférieur (24) présente une surface inclinée (26). Une bille mobile ferromagnétique (34) est placée entre les éléments (22, 24) et peut se déplacer le long de la surface (26), entre des positions espacées supérieure et inférieure d'actionnement d'interrupteur. Un aimant (36), conçu pour être monté sur le second élément (18), est orienté de façon à retenir normalement la bille (34) dans la position supérieure. Toutefois, en cas d'un mouvement de la structure (18), la bille (34) peut glisser vers le bas vers sa position inférieure.
