Title:
KEYBOARD SWITCH
Document Type and Number:
WIPO Patent Application WO/2017/121298
Kind Code:
A1
Abstract:
A balance mechanism (180) and a keyboard switch (100) comprising the balance mechanism (180) are provided, and relate to the technical field of keyboard switches. The balance mechanism (180) comprises a first frame (181) and a second frame (182) rotatable relative to each other. The first frame (181) and the second frame (182) are both hollow structures, and the shapes and sizes thereof match. When the first frame (181) and the second frame (182) are in a folded state, a moving contact (130) and a static contact (120) contact and electrically connect. When the first frame (181) and the second frame (182) rotate to form a X-shaped structure, the moving contact (130) and the static contact (120) separate. A relative rotation between the first frame (181) and the second frame (182) of the balance mechanism (180) drives the moving contact (130) to move, achieving separation and contact between the moving contact (130) and the static contact (120), thereby opening or closing the switch. The keyboard switch (100) is thin, achieving miniaturization of the switch, and the switch prevents a guide core (160) from being inclined and trapping the button, and the invention is also convenient to use.
