Abstract: A keyboard device includes a base plate and a key structure. The key structure includes a keycap, a first connecting element, a second connecting element and a stabilizer bar. The first connecting element and the second connecting element are arranged between the base plate and the keycap and connected with the base plate and the keycap.

Moreover, it is not necessary to retain the gap between the first base posit and the open-type hook. While the first frame is swung, the elastic contact part is pushed by the corresponding bulge. Consequently, the first base post is not detached from the base plate.

The control unit is electrically connected with the switching key and the bicolor light-emitting element. If the switching key is pressed down when the bicolor light-emitting element emits the first color light, a pressing signal is generated. In response to the pressing signal, the color light emitted by the bicolor light-emitting element is switched from the first color light to the second color light under control of the control unit.

After plural light beams pass through the elongated condenser structures in the upward direction, the beam angles of the light beams from the light guide plate are converged by the elongated condenser structures. Consequently, the brightness of the backlight is increased. Moreover, the light beams do not leak from the vacant spaces between adjacent key structures.
