La présente invention fournit le dispositif bistable qui comprend : un moteur d'entraînement ; un engrenage relié au moteur d'entraînement ; une tige de came ayant une extrémité accouplée à une surface de l'engrenage de manière à effectuer un mouvement de va-et-vient en fonction de la rotation de l'engrenage ; une clé de verrouillage accouplée à l'extrémité externe de la tige de came de façon à se déplacer linéairement ; et un ressort ayant une extrémité fixée à un boîtier et ayant l'autre extrémité fixée à l'autre surface de l'engrenage et qui maintient une première position stable, au niveau de laquelle le ressort est disposé dans une première direction normale de l'engrenage, de sorte que la clé de verrouillage fasse saillie au moyen du ressort, ce qui permet d'obtenir un état verrouillé, ou une seconde position stable, au niveau de laquelle le ressort est disposé dans une seconde direction normale de l'engrenage, de sorte que la clé de verrouillage soit rétractée, ce qui permet d'obtenir un état ouvert.
