Novel keyboard switch

Abstract

The invention discloses a novel keyboard switch which comprises an upper cover, a base, a fixed terminal, a movable terminal and a pressing piece, wherein the base is provided with a guide post; the pressing piece is connected to the guide post sleeved with a return spring; the upper end of the pressing piece protrude out of the upper cover for pressing; the upper cover is buckled with the base, so that a cavity between the upper cover and the base; the fixed terminal and the movable terminal are arranged in the cavity; one end of the fixed terminal and one end of the movable terminal penetrate out of the base and are connected with an external circuit; and the movable terminal is a metal contact sheet disposed on the base in parallel and can move up and down to contact with the fixed terminal, so that a switching function is achieved. According to the invention, the movable terminal transversely arranged on the base and the fixed terminal arranged on one side of the base in a matched manner are adopted and switching function is achieved by the contact of the movable terminal and the fixed terminal through the up-and-down movement of the moving terminal. The thickness of the novel keyboard switch can be reduced, so that the novel keyboard switch can be suitable for equipment requiring a light and thin keyboard design. Besides, the novel keyboard switch is simple in structure and low in cost, and production efficiency of enterprises can be improved.

Description

technical field [0001] The invention relates to an electronic switch, in particular to a novel keyboard switch. Background technique [0002] Many operations of existing devices require the use of key switches as input means. The quality of the key switch determines the experience of the input device, and it is necessary to ensure a good feel and service life. [0003] Most of the movable contacts made of metal sheets in the existing key switches are bent to form an elastic structure. This kind of movable contact is mainly formed by a bending part at the bottom to form elasticity to realize the movable contact. However, because Nowadays, keyboards or other mechanical switch input devices pay more and more attention to lightness and thinness. If the upper or lower part is bent to form elasticity, it needs to reserve a certain height because of the need to pursue a good feel and hinder the strength of the metal sheet. To achieve bending, it is not easy to make the product lig...

[0003] Most of the movable contacts made of metal sheets in the existing key switches are bent to form an elastic structure. This kind of movable contact is mainly formed by a bending part at the bottom to form elasticity to realize the movable contact. However, because Nowadays, keyboards or other mechanical switch input devices pay more and more attention to lightness and thinness. If the upper or lower part is bent to form elasticity, it needs to reserve a certain height because of the need to pursue a good feel and hinder the strength of the metal sheet. To achieve bending, it is not easy to make the product lighter and thinner, and the structure of this kind of moving contact piece is relatively complicated, and the production cost is relatively high
