Abstract

The invention relates to a detection switch. The detection switch comprises an isolated base, a torsional spring and an action bar, wherein a hollow boss, a hook, a first terminal, a second terminal and a third terminal are fixed on the isolated base, the first terminal, second terminal and third terminal do not contact; the torsional spring is sleeved to the periphery of the hollow boss of the isolated base; the action bar comprises a positioning column, a retaining wall and a operation part; the positioning column is pivoted in the hollow boss, the retaining wall is clasped with the hook of the isolated base, and a conducting plate is also fixed on the action bar. The action bar can be selectively rotated to a first position to ensure that the third terminal is electrically connected with the second terminal through the conducting plate, or the action bar can be selectively rotated to a second position to ensure that the first terminal is electrically connected with the second terminal through the conducting plate. Therefore, the invention has simple structure and less parts and components; and the mortise and tenon structure is used for connection, thus the assemble steps are less.

Description

technical field [0001] The invention relates to a detection switch, in particular to a detection switch suitable for electronic products such as optical drives. Background technique [0002] There are quite a variety of optical drive products, among which CD-ROM optical drive has become the mainstream of the market due to its mature technology and relatively cheap price, and it is an important equipment for personal computers. In addition, CD-ROM drives are divided into two types, one is a half-height CD-ROM drive (Half Height CD-ROM) for desktop computers, and the other is a thin CD-ROM drive (Slim-Type CD-ROM) for notebook computers. . [0003] Unlike desktop optical drives, slim optical drives have stricter requirements on stability, vibration, noise, weight, heat dissipation and power consumption. Since thin optical drives are mainly used in notebook computers, size and weight are important considerations for portability and ease of operation. [0004] Wherein, the de...
