Abstract

L'invention concerne un commutateur de clavier ultramince comprenant une base de montage (2) et un couvercle d'appui (8). Un module de micro-commutateur est disposé entre la base de montage et le couvercle d'appui. Quatre coins du couvercle d'appui sont respectivement pourvus d'une colonne (81) d'équilibrage et de positionnement. La base de montage est pourvue de trous de guidage (25) qui sont situés en correspondance avec les colonnes d'équilibrage et de positionnement du couvercle d'appui et qui servent à permettre aux colonnes d'équilibrage et de positionnement de les traverser et de se déplacer verticalement. La coopération mutuelle des colonnes d'équilibrage et de positionnement et des trous de guidage permet d'améliorer efficacement le degré d'équilibre et la stabilité, ce qui résout le problème de verrouillage de coins et prolonge la durée de vie du produit. L'utilisation du module de micro-commutateur permet d'utiliser entièrement l'espace interne du commutateur, de façon à maîtriser l'épaisseur du commutateur et à amincir le commutateur ; une ligne d'encliquetage (7) est en outre ménagée dans le commutateur et, par conséquent, à condition que le commutateur soit réalisé aussi petit que possible, le commutateur procure une bonne sensation tactile et un effet auditif lors du processus d'appui.
