Abstract

La présente invention concerne un commutateur ayant un toucher satisfaisant et comprenant un couvercle supérieur (1), une base (2), une borne fixe (3), une borne mobile (4) et une partie de pression (5). Un montant de guidage (21) est disposé sur la base. La partie de pression est installée sur le montant de guidage. Un ressort de réinitialisation (8) est emmanché sur ledit montant de guidage (21). Le couvercle supérieur de l'extrémité supérieure de la partie de pression est exposé de manière à être enfoncé. Une cavité est formée en cintrant le couvercle supérieur et la base. La borne fixe et la borne mobile sont disposées sur un côté de la partie de pression dans la cavité. Une extrémité de la borne fixe et une extrémité de la borne mobile s'étendent hors de la base de façon à se brancher à un circuit externe. Un déplacement de haut en bas de la partie de pression entraîne un déplacement de la borne mobile de manière à commander le branchement et le débranchement entre la borne mobile et la borne fixe. Un dôme tactile (6) est disposé sur l'autre côté de la partie de pression. Des nervures en saillie (53) sont disposées sur une surface latérale correspondante de la partie de pression. Le déplacement de haut en bas de la partie de pression entraîne un déplacement de la borne mobile d'une manière telle que les nervures en saillie appuient sur le dôme de façon à améliorer le toucher par pression. Le commutateur comprend également un indicateur clé (7) disposé sur la base. L'ajout du dôme tactile dans le commutateur confère au commutateur un toucher satisfaisant. En outre, le commutateur présente une structure simple et une plus longue vie utile.
