Dual-contact mechanical keyboard switch

Abstract

The present invention discloses a dual-contact mechanical keyboard switch. The dual-contact mechanical keyboard switch comprises a key pad, a key shaft and an upper cover; the key pad and the upper cover are in buckle connection and are assembled to a housing, the housing is provided with a holding groove configured to hold the key shaft, the key shaft is movably inlaid in the holding groove, thetop end of the key shaft is extended out of the holding groove and the upper cover and then is fixedly connected with a key cap, the shaft core of the key shaft movably penetrates the key pad and thenis extended, and the shaft core of the key shaft is sleeved with a spring movably connected with the key pad; a static wafer is fixedly arranged at the side of the matching key shaft in the holding groove, two movable wafers are arranged beside the static wafer side by side, the two movable wafers are both provided with contacts being in movable contact with the static wafer, the two contacts arelocated in a straight line in a vertical direction, the two movable wafers are both provided with drive portions in an extrusion mode configured to be in movable contact with the key shaft and butt against the movable wafers to allow the two contacts to be synchronously flicked with the static wafer, and the two drive portions are located in the same height position in the vertical direction. Thedual-contact mechanical keyboard switch is compact in structure, good in contact, good in stability and long in service life.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a double-contact mechanical keyboard switch. Background technique [0002] With the continuous improvement of people's lives, the use of computers has become more and more popular in society, and has become an indispensable item in people's lives. As an indispensable input device for computers, the keyboard has more and more functions and types. The keyboard is a frequently used computer peripheral device, and its operating performance has been gradually improved with the continuous innovation of technology. From mechanical to Optoelectronics, from optoelectronics to optics, from wired to wireless, the reliability and functionality of keyboards are getting better and better. [0003] A Chinese patent for a mechanical keyboard switch (patent number: 201320172454.8) discloses a mechanical keyboard, which includes a key base, a handle and an upper cover. There is a pos...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned 201320172454.8 patent discloses a relatively conventional mechanical keyboard in the existing market, and the keyboard switches in the current market all use one-point contact type, and the disadvantage of the one-point contact type keyboard switch is that there is a phenomenon of unstable contact with one-point contact. , so that it cannot guarantee its stability in long-term use, and in the long-term use process, the contacts will be worn and cause the keyboard switch to miss touch and not work
