Abstract

Un dispositif clavier (300) est décrit aux présentes, lequel dispositif clavier (300) comprend un substrat (200) et une pluralité de dômes (302) positionnés sur le substrat (200) et configurés pour traduire l'action de l'opérateur en une entrée correspondante pour une machine. Le dispositif clavier (300) comprend également un protecteur de dômes (330) positionné sur les dômes (302) et le substrat (200) sur lequel le protecteur de dômes (330) peut créer un environnement scellé pour le substrat (200) et les dômes (302). Un guide de lumière (320) qui dirige la lumière dans le dispositif clavier (300) et une composante de blocage (335) couplée au guide de lumière (320) peuvent également faire partie du dispositif clavier (300). Dans une réalisation, la composante de blocage (335) peut sélectivement comprimer le protecteur de dôme (330) pour contribuer à créer un environnement scellé. Dans une autre réalisation, la composante de blocage (335) peut comprimer le protecteur de dômes (330) en courbant le protecteur de dômes (330) à un rebord (210) du substrat (200).
