A backlight module including a light guide plate, a circuit board, an electronic component, a reflective sheet, a light-shielding sheet, and a light-emitting component is provided. The light guide plate includes an escape opening and a light-source opening. The circuit board is disposed under the light guide plate. The electronic component is electrically connected to the circuit board, and at least a part of the electronic component is located in the escape opening. The reflective sheet is disposed on a rear surface of the light guide plate and between the light guide plate and the circuit board. The light-shielding sheet is disposed on a light emitting surface of the light guide plate opposite to the rear surface. The light-emitting component is disposed in the light-source opening. A luminous keyboard using this backlight module is also provided.

A keyswitch includes a bottom board, a cap structure, a lifting mechanism, and an elastic member. The lifting mechanism is detachably connected to the cap structure and the bottom board to make the cap structure movable upward and downward relative to the bottom board. The elastic member is connected to the cap structure so as to be detached from the lifting mechanism together with the cap structure when the cap structure is separate from the lifting mechanism.

When an occupant has performed a specific operation that is an operation different to an input operation on a state switching section while in a state in which a display section capable of displaying information related to an input section is not displaying the information, a processor causes the information to be displayed on the display section and places the input section in an input enabled state in which the input operation is receivable. Moreover, when the occupant has not performed the specific operation on the state switching section while in state in which the information is not being displayed on the display section, the processor does not cause the information to be displayed on the display section and places the input section in an input disabled state in which the input operation is not receivable.

A keyboard device includes a casing, a circuit board, plural keys and an electrostatic conduction module. The circuit board is disposed within the casing. The circuit board includes a ground terminal. The plural keys installed in the corresponding key slots of the casing. The electrostatic conduction module includes a first conductive element, an elastic conductive element and a second conductive element. The first conductive element is installed on a keycap of the key. The elastic conductive element is disposed within the casing and contacted with the circuit board. The second conductive element is connected between the first conductive element and the elastic conductive element. Moreover, electrostatic charges on the keycap are transferred to the circuit board through the first conductive element, the second conductive element and the elastic conductive element and discharged from the ground terminal of the circuit board.

A dome switch button is installed on a circuit board. The dome switch button includes an elastic piece, a conductive piece and a buffering element. The elastic piece is located over the conductive piece. The buffering element is located under the conductive piece and electrically connected with the circuit board. When the elastic piece is subjected to elastic deformation to trigger the conductive piece, an electric signal is generated. The buffering element is electrically connected with the circuit board. Moreover, a first electric pad and a second electric pad of the circuit board are covered by the buffering element. The electricity from the first electric pad and the second electric pad of the circuit board can be transferred to the conductive piece through the buffering element. Consequently, the conductive piece can be electrically connected with the circuit board without the need of using additional conductor lines.

One embodiment provides a device, including: a mechanical keyboard; a key state component mechanically co-located with each of a plurality of keys of the mechanical keyboard, wherein the key state component changes state between at least actuated and unactuated; a processor; a memory device that stores instructions executable by the processor to: detect an input to change a state of the key state component for at least one of the plurality of keys; and change, responsive to the input, the state of the key state component for the at least one of the plurality of keys.

A key structure includes a bottom plate, at least one keycap, and a thin-film circuit board. The bottom plate has at least one elastic protruding portion. The keycap is liftably connected to the bottom plate and has a press portion and at least one trigger portion. The press portion is located at a central region of the keycap and faces the elastic protruding portion, and the trigger portion is located at a peripheral region of the keycap. When the key is lowered from a first position to a second position relatively to the bottom plate, the press portion downwardly presses the elastic protruding portion, and the press portion triggers an electrical trigger point of the thin-film circuit board. The keycap is adapted to be restored from the second position to the first position through an elastic force of the elastic protruding portion.
