Problems solved by technology

[0003] However, in order to reduce friction and make sliding more smoothly during use, the existing sliding switch device is often not tightly matched with the portable electronic device, and there may be a large gap between the two, and moisture, dust and other impurities from the outside Objects will enter the portable electronic device through the gap, and the sound from the audio device of the electronic device will also leak out of the gap, resulting in poor sound quality, thereby affecting the overall performance of the portable electronic device

Abstract

The invention discloses a switching device, mounted in an electronic apparatus. The switching device comprises a housing, an accommodating chamber formed in the housing, a slide button disposed in theaccommodating chamber and a spring provided on the slide button. The accommodating chamber is used for accommodating a printed circuit board in the accommodating chamber, the printed circuit board isprovided with a plurality of metal regions for connecting to other circuits of the electronic apparatus, the slide button is supported at the inner side of the housing under the spring action of thespring, one end of the spring slides under the drive of the slide button and can slide on one of the metal regions, while the other end can slide between other metal regions, and can be selectively supported to one of the other metal regions, so that the electronic apparatus is located at different function states.

Description

technical field [0001] The invention relates to a switch device, in particular to a switch device applied to a portable electronic device. Background technique [0002] In recent years, with the development of wireless communication and information processing technology, various electronic devices such as personal computers, mobile phones, and personal digital assistants (PDA) have emerged, allowing consumers to fully enjoy the high-tech technology anytime, anywhere. various conveniences. At the same time, the functions of these electronic devices are becoming more and more diversified. In practical applications, electronic devices need to switch between different functional modes. There is a switch device for the convenience of consumers. Most of these switch devices are sliding switches that are easy to operate. When in use, you only need to slide them between different positions to connect different circuits respectively, so as to realize the switching operation of diff...
