Key switch

Abstract

The invention discloses a key switch, which comprises a key cap, a shell, a shaft body and an elastic piece, wherein the shaft body is arranged in the shell in a penetrating way; one end of the elastic piece is connected to the shaft body; the other end of the elastic piece is connected to the shell; the key cap covers the shaft body; when the key cap is pressed, the key cap drives the shaft body to move relative to the shell; the key switch also comprises a film circuit and a conduction piece; the film circuit is arranged on one end, far away from the key cap, of the shell; the film circuit is provided with a conduction point; when the key cap is pressed, the shaft body drives the conduction piece to contact with the conduction piece to trigger the film circuit to generate signals. The key switch not only has the use performances such as good handfeel of the existing mechanical keyboard, high press service life and rapid conduction speed, but also solves the problems that the existing mechanical keyboard is not waterproof, is easily oxidized and is high in cost; the manufacturing and assembling technologies of the existing mechanical keyboard are simplified.

Description

technical field [0001] The invention relates to the technical field of mechanical keyboards, in particular to a key switch of a mechanical keyboard. Background technique [0002] The key switch of the mechanical keyboard is conducted by means of metal contacts riveted on two metal shrapnels. The manufacturing process of the key switch is complicated and the cost is high, and the metal shrapnel pins are welded on the PCB board. There is no barrier, so when the user accidentally splashes water on the keyboard, the water will flow into the keyboard along the gap between the key switches, resulting in a complete short circuit of the mechanical keyboard instantly, and its function and life cannot be effectively guaranteed . Therefore, the key switch of the current mechanical keyboard cannot solve the waterproof problem. In addition, in seasons with high air humidity or when the keyboard is used for a long time, its metal contacts and pin solder points are easily oxidized, resul...
