Description

Technical Field

[0001] This utility model relates to the field of keyboard technology, specifically to a keyboard inductive shaft. Background Technology

[0002] As an innovation in mechanical keyboard technology, the keyboard inductive switch, with its unique electromagnetic induction principle and excellent performance, provides a new option for users seeking an efficient and stable experience. Traditional keyboard switches have some design shortcomings, especially in terms of user experience. One significant problem is that they usually achieve key action by impacting the side ribs against the housing. This design often produces significant noise and strong vibration. During prolonged use, this design may cause hand fatigue or discomfort for users, as each key press is accompanied by noticeable vibration and impact. A utility model patent application (CN202422702061.4) describes a central inductive switch and keyboard. Its innovative design lies in its unique guiding and shock-absorbing structure, which consists of two side ribs and an elastic impactor. This structure aims to improve the tactile and acoustic experience of traditional buttons, reduce noise, and make the buttons quieter. However, this inductive switch still has some shortcomings in its use: the button moves up and down between the two side ribs and the base. Because there is no limiting structure between the other two sides of the button and the base, the button wobbles during its up-and-down movement, leading to increased noise and affecting the user experience after prolonged use.
