Abstract

Une structure de bouton comprenant un module tactile à force, selon la présente invention, comprend : un boîtier ayant une surface de plancher et un trou de bouton et fournissant un espace interne entre ceux-ci ; un module de reconnaissance d'empreinte digitale inséré dans le trou de bouton de façon à être exposé sur l'extérieur du boîtier ; le module tactile à force étant disposé dans l'espace interne du boîtier de façon à détecter un événement tactile de force appliqué au module de reconnaissance d'empreinte digitale ; et un poussoir fixé au module de reconnaissance d'empreinte digitale de façon à transférer, au module tactile à force, une pression générée par l'événement tactile à force du module de reconnaissance d'empreinte digitale. La présente invention peut réduire au minimum l'espace interne en ne nécessitant pas d'espace pour une structure séparée pour un commutateur à dôme et peut avoir une durée de vie semi-permanente à la différence d'une structure de commutateur à dôme étant donné qu'un signal électrique est utilisé.
