Keyboard Button Structure

Abstract

A keyboard button structure includes a flexible board and a key cap. The flexible board includes an hollow-out body, a first support portion, a second support portion, and an extending arm including a conducting contact. The first supporting is connected to the hollow-out body. A first perpendicular distance is formed between the first support portion and the hollow-out body. The second support portion is connected to the first support portion. The extending arm is connected to the second support portion. A second perpendicular distance is formed between the extending arm and the hollow-out body. The key cap is fixed to the first and the second support portions, and is rotatably coupled to the hollow-out body. When the key cap is moved in a direction toward the hollow-out body by an external force, the extending arm is moved in the direction with the key cap.
