Definitions

  • the push button switch is a switch widely used on the keyboard.
  • the main structure of the switch includes a base, an upper cover, a static contact piece, a movable contact piece and a guiding core, and the upper cover and the base are enclosed to form a receiving cavity, and the static contact piece, the movable contact piece and the guiding core are arranged In the accommodating cavity, one end of the guiding core is exposed outside the accommodating cavity, and the guiding core is pressed by pressing, so that the guiding core moves up and down, and then acts on the movable contact piece through the guiding core, so that the movable contact piece contacts the static contact piece. Connected or disengaged to achieve the on and off functions of the push button switch.

Abstract

L'invention concerne une touche contact de type mince, comprenant une rainure de réception, un point de conduction A et un point de conduction B étant disposés au fond de la rainure de réception. La touche contact comprend en outre un corps élastique de conduction disposé dans la rainure de réception, un noyau de guidage disposé mobile dans la rainure de réception et situé sur le corps élastique de conduction, et un couvercle enveloppant au niveau de la partie supérieure du noyau de guidage et recouvrant la rainure de réception; la partie centrale du corps élastique de conduction forme une courbe vers le haut pour former une protubérance en forme de fond de pot, le point de conduction A entre en contact avec un bord du corps élastique de conduction, et le point de conduction B est situé au-dessous de la protubérance en forme de fond de pot; par pression appliquée vers le bas au noyau de guidage, la pression est transférée à la protubérance en forme de fond de pot au niveau de la partie centrale du corps élastique de conduction, et la protubérance en forme de fond de pot se déforme de façon à venir en retrait vers le bas puis entre en contact avec le point de conduction B, ce qui permet d'obtenir une fonction de conduction; puis la protubérance en forme de fond de pot rebondit du fait d'une force de rappel élastique, et la protubérance en forme de fond de pot se sépare du point de conduction B, ce qui permet d'obtenir une fonction de déconnexion.
