Embodiment Construction

[0057] Figure 1A It is a schematic cross-sectional view of a button structure according to an embodiment of the present invention. It is explained here that the button structure of the embodiment of the present invention is applied to one of the buttons of the input unit (such as a keyboard) of an electronic device such as a computer to trigger a specific signal. Please refer to Figure 1A , the button structure 100 of this embodiment includes a housing 110 , a shaft body 120 , a first magnetic component 150 and a second magnetic component 160 . The casing 110 has a bottom 114 and a top 113 opposite to each other, and has a first opening 111 at the top 113 . The bottom 114 and the top 113 are connected to each other, for example, and define a hollow accommodating space for accommodating the shaft body 120 . The shaft body 120 is assembled on the casing 110 through the first opening 111 , and the shaft body 120 is adapted to be pressed to move along a pressing direction P fro...

Abstract

A key structure comprises a shell, a shaft body, a first magnetic assembly and a second magnetic assembly. The housing has a bottom and a top opposite to each other, and has a first opening at the top. The shaft body penetrates through the first opening to be assembled on the shell, and the shaft body is suitable for being pressed to move in the pressing direction from the top to the bottom. The first magnetic assembly is arranged on the shaft body. The second magnetic assembly is arranged on the shell, and the first magnetic assembly and the second magnetic assembly are located on the inner side and the outer side of the shell respectively.

Description

technical field [0001] The present invention relates to a mechanical switch structure, and in particular to a button structure. Background technique [0002] The keyboard is currently one of the most important input units for personal computers, notebook computers and mobile devices. According to the key structure of the keyboard, it can be simply divided into membrane keyboard and mechanical keyboard. The membrane keyboard mainly uses the rubber cap to be pressed to conduct the circuit under the rubber cap to generate a key signal. The membrane keyboard has the advantages of simple structure and low cost, and its membrane circuit has the advantage of being waterproof due to the integrated design. However, the pressing feel of the membrane keyboard is provided by the rubber cap being pressed and its restoring force, and the rubber cap will age over time, resulting in poor durability and further affecting the typing feel. [0003] On the other hand, in the key structure of...
