Embodiment Construction

[0033] As described in the above-mentioned known technologies, in order to improve the key-press sound generated by the micro switch, the present invention provides a micro switch, which can reduce the sound generated when the micro switch is operated.

[0034] Please refer to Fig. 2(a) and Fig. 2(b), which are schematic diagrams of separation of the upper cover and the base of the micro switch of the present invention. The micro switch 200 includes a base 201 , an upper cover 202 , and a pressing member 210 . The base 201 is provided with a common end 205 , a normally open end 207 , a normally closed end 208 and an elastic piece 209 . The upper cover 202 has a perforation 203 , and two short sides around the perforation 203 are impact portions 204 . In the micro switch 200 of the present invention, the shared end 205 is disposed at one end of the base 201 , and the shared end 205 has a protrusion 206 . The normally open end 207 is located at the other end of the base 201 , a...

Abstract

The invention relates to a micro-switch, comprising a base, an upper cover, a sharing end, a continuously open end, a continuously close end, a spring plate and a pressing piece. The upper cover is provided with a punch hole and a striking portion, the sharing end is disposed at one end of the base and is provided with an emboss, the continuously open end is disposed at the other end of the base, the continuously close end is disposed at the lateral edge of the continuously open end, one end of the spring plate is connected with the emboss, and the other end of the spring plate is contacted with the continuously close end, and the pressing piece is provided with a key-press portion and a flange, wherein the key-press portion passes through the punch hole thereby enabling the flange to be contacted with the striking portion, further, the striking portion and the flange of the pressing piece is produced by shock absorption materials. The micro-switch of the invention can reduce sound generated when operating the micro-switch.

Description

technical field [0001] The invention relates to a micro switch, in particular to a micro switch capable of reducing sound. Background technique [0002] In today's information age, computers and other electronic equipment have already been popularized. Almost every family has more than one computer, and the mouse is responsible for connecting the computer and the user. Its importance is beyond doubt. Therefore, in recent years, related The number of inventions such as the improvement of the mouse device is increasing year by year. [0003] Whether it is a mechanical mouse or an optical mouse, there are left and right buttons. When the user touches the left and right buttons of the mouse, the microswitches below the buttons will be triggered to generate corresponding control commands. However, a loud sound will be produced when the known micro switch is pressed. In some cases, such as multiple people operating the mouse in the same conference room, the sound produced by the ...
