The present invention provides a keyboard. The keyboard includes a circuit board, a key installing board, and a plurality of key switches, the circuit board is disposed opposite the key installing board, the key installing board is provided with a plurality of installation holes corresponding to the key switches, the plurality of key switches are movably clamped on the key installing board through the plurality of installation holes, each of the key switches has a conductor, the conductor extends in the direction of near the circuit board through an installation hole, the circuit board is provided with a plurality of connection terminals working with conductors of the plurality of key switches, the conductors of the plurality of key switches are contacted with the plurality of connected terminals of the circuit board. The key switches of the keyboard of the present invention are moveable, elongating use-life of the keyboard.

An illuminated keyboard with an optical switch is provided. The illuminated keyboard includes a circuit board and plural keys. The circuit board includes plural light-emitting elements. Each light-emitting element is aligned with the corresponding key. The key includes a keycap, a housing, a triggering post, a light guide element and a light guide frame. The keycap is located over the housing. The triggering post, the light guide element and the light guide frame are disposed within the housing. Moreover, the light guide frame is arranged around the triggering post. After a light beam emitted by the light-emitting element is introduced into the housing, the light beam is guided to the light guide frame by the light guide element, and the light beam is scattered to a region around the triggering post and outputted from the keycap.

An input device includes an upper cover including a plurality of key openings and a keyboard including a base plate disposed on a back side of the upper cover, and a plurality of key tops provided in a front side of the base plate and inserted in the respective key openings. A plurality of hooks, each of which is disposed between the key tops adjacent to each other at a plurality of points and is provided upright on a back surface of the upper cover, fixes the keyboard to the upper cover.
