Keyboard structure

Abstract

A keyboard structure including a base, a frame and several keys is provided. The frame is disposed on the base. The keys are disposed on the base and are separated from each other by the frame. From top to bottom, each key sequentially includes a cap, a limiting structure, an elastic member and a diaphragm switch element. The elastic member is disposed on the diaphragm switch element, the cap is disposed on the elastic member, and the limiting structure is engaged with the cap, such that the cap can move relative to the diaphragm switch element in a vertical direction. The surrounding surface of the cap has a flange, which contacts the bottom of the frame in the vertical direction. Thus, dusts or moisture can hardly infiltrate the keyboard structure and the waterproof and dustproof functions of the keyboard structure can be improved.

Dependencies are inferred from the claim text.
