Abstract

La présente invention concerne un commutateur de haute productivité dans lequel un bouton à pression peut être monté après incorporation de composants internes dans un logement. A cette fin, un bouton à pression (90) est inséré dans un trou fonctionnel (14) dans un logement (10) de sorte qu'une saillie de mise en prise (91) disposée sur la partie de bord d'extrémité inférieure du bouton à pression (90) est mise en prise avec une première rainure de mise en prise (17) disposée sur la surface de périphérie interne du trou fonctionnel (14). En outre, ladite saillie de mise en prise (91) qui traversait ladite première rainure de mise en prise (17) pousse une coulisse (60) vers le bas tout en faisant tourner ledit bouton à pression (90). Ensuite, la saillie de mise en prise (91) dudit bouton à pression (90) est mise en prise avec une seconde rainure de mise en prise (64) qui est disposée sur la surface de périphérie interne d'une partie évidée (63) de ladite coulisse (60), ladite coulisse (60) se déplace de ce fait vers le haut et maintient ledit bouton à pression (90) en place.
