A light beam from the illumination module passes through the light-transmissible region. Consequently, the key structure is illuminated.

Abstract: An operating mechanism including a number of biasing elements and a number of linkage members is provided. The linkage members are operatively coupled to each other and each are movable between a second configuration, an initial tripped configuration, a rebound configuration, and a final tripped configuration. The biasing elements are operatively coupled to the number of linkage members and bias the number of linkage members to the final, first configuration. A stop member is coupled to one of the linkage members. The stop member moves with the associated linkage member. The stop member is positioned to contact a stop surface when the linkage members are in the rebound configuration. Contact between the stop member and the stop surface substantially arrests the motion of the linkage members.

Abstract: A rocker input mechanism includes an actuator that is operable to pivot against the interior surface of a housing through which an actuation surface of the actuator projects. Pivots or up-stops on the edges of the actuator are biased against the interior surface by dome switches contacting a switching surface of the actuator that is opposite the actuation surface. Thus, the actuator is able to pivot with respect to the interior surface to activate the dome switches when force is exerted on the actuation surface without bending or flexing like typical rocker buttons. As a result, the rocker input mechanism may have a feel to a user similar to non-rocking input mechanisms like single mode buttons.

Abstract: A keyswitch structure includes a base, a keycap, a frame disposed between the base and the keycap for providing a supporting and moving mechanism to the keycap, and another frame interacting with the former frame through a magnetic attraction force. When the keycap is not pressed, the magnetic attraction force drives the two frames to stably stand on the base and form a stable supporting structure, so that the keycap is located at a farther position relative to the base. When the keycap is pressed with an external force to move toward the base, the magnetic attraction force is overcome so that the two frames depart from each other; that is, the above stable supporting structure is temporarily destroyed. Once the external force applied to the keycap is eliminated, the two frames will form the stable supporting structure again due to the magnetic attraction force.

The stabilizer bar is connected with the keycap and the soft fixing element. The soft fixing element is disposed on the base plate. The soft fixing element has an accommodation space.

Consequently, the soft fixing element is firmly fixed on the base plate. Since the metallic stabilizer bar and the metallic base plate are separated by the soft fixing element, the keyboard device is capable of reducing noise.
