Small mechanical keyboard switch

Abstract

The invention discloses a small mechanical keyboard switch. The small mechanical keyboard switch comprises a base, the top end of the base is provided with a cover plate; the inner bottom surface of the base protrudes upwards and is provided with a locating shaft; the locating shaft is sleeved with a spring; the top end of the spring is provided with a central spindle; the base is provided with a fixed terminal, a movable terminal, and a LED lamp; both the fixed terminal and the movable terminal are in horizontal structures; the movable terminal comprises a movable contact pin and a movable contact ring which is connected at the upper portion of the movable contact pin; the surface of the movable contact ring close to the fixed terminal is provided with a movable terminal contact; the fixed terminal comprises a fixed contact pin; the top end of the fixed contact pin is connected with a spacing table; the spacing table protrudes upwards and is provided with a fixed hook; and the fixed hook is provided with a fixed terminal contact. By the movable terminal configuration of the annular movable contact ring structure, the purpose of greatly reducing the height of the product can be achieved by comparing with the conventional movable contact piece structure; the contact piece is in horizontal structure; the transverse space is used for increasing the force arm of the spring piece, thereby increasing the elastic coefficient, the service life, and the stability; the small mechanical keyboard switch is compact in structure, convenient in machining and assembling; therefore the product is miniaturized; and the consumers like the product more.

Description

technical field [0001] The invention relates to a small mechanical keyboard switch with a compact structure, stable operation and a horizontal moving contact ring structure. Background technique [0002] Chinese patent application number: 201320172454.8, discloses a mechanical keyboard switch, including a key base, a handle and an upper cover. There is a concave cavity in the key base, and a positioning post is provided on the lower end of the key base. The positioning groove is connected with a return spring, one end of the return spring is connected with the positioning column, the other end is connected with the handle, the upper cover is fastened with the key base to form a cavity, and a static contact piece and a dynamic contact piece are arranged in the cavity. The contact piece includes integrally formed welding parts and contact parts, the moving contact piece includes fixing parts and welding parts, the welding parts of the static contact piece and the welding parts...
