Abstract

Un commutateur de clavier pouvant être pressé vers le bas d'une manière équilibrée comprend une base (1) et des dessus de touche (2) fixés sur la base. Un mécanisme de déclenchement de borne de commutateur est installé entre la base et les dessus de touche. Le mécanisme de déclenchement de borne de commutateur est pressé par pression d'un dessus de touche, de manière à permettre aux bornes du mécanisme de déclenchement de borne de commutateur d'être connectées ou déconnectées pour mettre en œuvre la fonction du commutateur. Des trous de guidage (11) sont disposés sur les côtés de la base, et des colonnes de guidage (21) sont disposées sur les dessus de touche correspondants. Les dessus de touche et la base sont connectés au moyen de structures de serrage, ou les dessus de touche et le mécanisme de déclenchement de borne de commutateur sont connectés au moyen de structures de serrage. Dans le commutateur de clavier, les dessus de touche et la base assurent l'équilibre et la stabilité du commutateur à l'aide de structures d'appariement des colonnes de guidage et des trous de guidage, et les opérations qui ne sont pas sans à coups provoquées par une force non équilibrée peuvent être évitées de manière efficace lors de l'utilisation ; en outre, les dessus de touche et la base sont connectés par l'intermédiaire des structures de serrage ou les dessus de touche et le mécanisme de déclenchement de borne de commutateur sont connectés au moyen des structures de serrage, ce qui permet d'assurer la stabilité des dessus de touche et de faciliter le démontage et le remplacement.
