Abstract

Cette invention se rapporte à un dispositif commutateur à deux étages dont la taille est réduite et dont le montage est simplifié, qui permet un réglage aisé de la course cible et de la sensation de clic dans la phase de conception et qui crée une sensation de clic nette. A cet effet, un dessus de touche (5) est formé en une seule pièce au dessus d'un espace entouré par une paroi périphérique droite (3), en passant par une première section de déformation (4) pouvant subir une déformation élastique verticale, comportant sur sa surface inférieure une première section commutateur (6), une seconde section commutateur (7), et une seconde section de déformation (11) pouvant subir une déformation élastique verticale pas à pas. Un contact mobile (8) situé à l'extrémité inférieure de la première section commutateur est disposé au dessous du niveau d'un contact mobile (9) situé à l'extrémité inférieure de la seconde section commutateur. La première section de déformation se déforme sous une force de pression de premier étage exercée sur le dessus de touche, amenant ainsi le contact mobile de la première section commutateur en contact avec un premier contact fixe (13). La seconde section de déformation se déforme sous une force de pression de second étage, amenant le contact mobile (9) de la seconde section commutateur en contact avec un second contact fixe (14). Lorsqu'on relâche la pression, les deux sections de déformation retrouvent par élasticité leur configuration, ramenant ainsi le dessus de touche dans sa position d'origine.
