Problems solved by technology

[0004] The buttons of the mechanical keyboards on the market all adopt the contact buttons formed by the conduction between the contact sheet and the contact sheet. The existing contact button has the disadvantage that: the existing keyboard switch can only be a single switch. Conduction, that is, it can only be in two states of conduction and disconnection. In this way, the keyboard input function will be single, and the experience will not be strong; at the same time, most of the existing keyboard switch conduction strokes are fixed and cannot be set. The stroke of the button conduction or multi-point stroke conduction, moreover, the existing contact button still has the problem of poor product consistency due to the difference of the contact shrapnel, and the use effect is not good

Abstract

The invention discloses a non-contact shaft of a button and the button. The non-contact shaft is provided with a center shaft body, wherein the top of the center shaft body is provided with a keycap seat, the center shaft body can extend into a key seat of the button, the keycap seat can be pressed to make the center shaft body reciprocate in a vertical direction in the key seat, the center shaftbody is provided with a cylindrical boss that divides the center shaft body into two halves, and the lower half of the center shaft body is provided with a return spring by penetrating; the non-contact shaft further comprises an optical displacement sensor mounted on a PCB circuit board disposed at the bottom end of the key seat, the optical displacement sensor is disposed at a position opposite to the central axis of the center shaft body and can sense and / or detect the displacement and position of the vertical movement of the center shaft body, and when the displacement and position of the vertical movement of the center shaft body match the displacement and position corresponding to a set conduction condition, the non-contact shaft is typed in.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to a non-contact shaft of a key and the key. 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] The keyboard is the most commonly used and the most important input device in the computer system. By tapping the keys on the keyboard, the contacts are turned on or off, so that letters, n...
