Keyboard switch

Abstract

A balance mechanism (180) and a keyboard switch (100) including the balance mechanism (180) are provided. The balance mechanism (180) comprises a first frame (181) and a second frame (182) rotatable relative to each other, which are both of hollow structures with matched shapes and sizes. When the first frame (181) and the second frame (182) are in a superimposed state, a dynamic contact (130) and a static contact (120) are electrically connected. A relative rotation between the first frame (181) and the second frame (182) drives the moving contact (130) to move, achieving separation and contact between the dynamic contact (130) and the static contact (120), thereby turning on and off the switch. The keyboard switch (100) is thin, thus achieving miniaturization of the switch; the switch prevents a guide core (160) from tilting and being stuck in the button, which is convenient for operation.
