Problems solved by technology

[0003] In addition, the internal structure of the existing shrapnel switch is complicated and chaotic, and the shrapnel is easy to loosen and bounce off, which greatly affects the performance of the switch. At the same time, its sensitivity is poor and cannot achieve an accurate sensitivity level. Therefore, it is necessary to design a safe, simple structure and Responsive shrapnel microswitch

Abstract

The invention discloses a spring-plate-based micro switch comprising a housing. An operation button is arranged at the upper part of the housing and penetrates the housing. A steel plate, a spring plate, a normally-closed contact, and a normally-open contact are arranged inside the housing; the steel plate is embedded into the inner wall of the housing and is fixed with the housing; and a spring hook is arranged at the left side of the steel plate and is fixed with the operation button. A spring and a copper bead are arranged on the spring plate; the spring is arranged at the left end of the spring plate; and the copper bead is fixed at the right end of the spring plate. The normally-closed contact is arranged at the upper right side of the spring plate; a base plate is arranged above the normally-closed contact; and a cone is arranged below the normally-closed contact and the normally-open contact is arranged at the lower right side of the spring plate. The micro switch has advantages of safety electrification, simple structure, and sensitive reaction.

Description

technical field [0001] The invention relates to a shrapnel micro switch. Background technique [0002] In a modern information society with highly developed information and communication systems, electronic devices are widely used in various fields, such as mobile phones, MP3 and PDA, and other electronic products are widely used in daily life, and people can exchange information anytime and anywhere with the help of mobile phones , experience sharing and communication of opinions, while MP3 can bring entertainment and relax people. With the increasing popularity of electronic equipment, the increasing maturity of technology, the increasingly changeable appearance and the decreasing volume, how to improve the usability of the operating keyboard of electronic products has become one of the important issues in current design. [0003] In addition, the internal structure of the existing shrapnel switch is complicated and chaotic, and the shrapnel is easy to loosen and bounce o...
