Abstract

La présente invention aborde le problème consistant à fournir un procédé capable de répondre à une demande d'utilisation d'un commutateur à bascule à diverses fins en raccourcissant la taille entière du commutateur à bascule, et l'amélioration de la stabilité d'un état excité par l'augmentation d'une force de contact au contact du commutateur à bascule. Afin de résoudre ce problème, des ressorts hélicoïdaux 12 subissent de manière répétée une compression ou une libération conformément à une opération de pression. Une partie de montage 112 est disposée sur un bouton 11 de manière à s'adapter à une extrémité de chacun des ressorts hélicoïdaux 12. Une pièce de charge 131 est disposée sur une pièce de contact mobile 13, est ajustée à l'autre extrémité de chacun des ressorts hélicoïdaux 12, et transmet de l'énergie élastique générée par compression ou relâchement des ressorts hélicoïdaux 12 à la pièce de contact mobile 13. La pièce de contact mobile 13 oscille en utilisant l'énergie élastique transmise tandis qu'un point de contact sert de point de support S tandis que le point de contact est déplacé.
