Abstract: A keyboard device includes a membrane circuit board, a base plate and a key. The key includes a keycap, a connecting element and a stabilizer bar. The connecting element is connected between the keycap and the base plate. The stabilizer bar is connected between the keycap and the connecting element. While the keycap is moved upwardly or downwardly relative to the base plate, the stabilizer bar is swung to stabilize the key. Since the stabilizer bar is connected between the keycap and the connecting element, the stabilizer bar does not readily collide with or knock on the base plate. During the process of operating the key, the generated noise is reduced. Consequently, the operating comfort to the user is enhanced.
