The switch structure provided in a control device of a vehicle ceiling part comprises a cover that is openable and closable between a closed position to cover a switch and an opened position to open the switch, and in the cover, a region that covers an operation surface of an operation element of the switch in at least the closed position is formed of a member that transmits light, and the cover has a top surface comprising an inclined portion inclined at an upward gradient from a vehicle front toward a vehicle rear in the closed position.

A light-emitting keyboard includes a bracket, a keycap, a circuit layer, a composite light-emitting layer and a spacing layer. The bracket has an opening. The keycap is disposed on the bracket and connected to the bracket via a support assembly. The circuit layer is disposed between the keycap and the bracket. The composite light-emitting layer is disposed under the bracket, and includes a substrate, a circuit disposed on the substrate and a light source located under the keycap and electrically connected to the circuit, wherein light emitted from the light source is transmitted upwardly to the keycap. The spacing layer is disposed between the composite light-emitting layer and the bracket, wherein the spacing layer includes a hole corresponding to the opening of the bracket, and the light source is located in the hole of the spacing layer.

A key module including a base, a circuit layer, at least one light-transmission key body, and a display panel is provided. The circuit layer is disposed at the base and has at least one input portion. The light-transmission key body has an abutting end and a pressing end opposite to each other. The abutting end abuts the base, and the light-transmission key body is adapted to be pressed downward by taking the abutting end as a rotation axis, such that the pressing end presses the input portion. The display panel is disposed at the base and has at least one display region, the display region is aligned with the light-transmission key body, and an image displayed on the display region by the display panel is changeable.

A light-emitting keyboard is provided, including a bracket with at least one opening, a keycap, a circuit layer, a light guide plate, and a composite light-emitting layer. The keycap is connected to the bracket via a support assembly. The circuit layer is disposed between the keycap and the bracket. The light guide plate is disposed under the bracket. The composite light-emitting layer disposed under the bracket has a light-shielding pattern. The composite light-emitting layer includes a light-transmitting substrate, a first circuit, a first light source, and a first passivation layer. The first circuit is disposed on one side of the light-transmitting substrate. The first light source is disposed on one side of the light-transmitting substrate and electrically connected to the first circuit. The first passivation layer covers the first circuit, and at least a portion of the first circuit is located between the first passivation layer and the light-transmitting substrate.

A membrane keyboard structure and a conductive method thereof allows a first surrounding portion of a first flexible circuit layer to be deformed to pass through an through hole to be in direct contact and conduction with a second surrounding portion temporarily when it is pressed through the coordination of a first flexible sheet body, first flexible circuit layer configured on the first flexible sheet body, spacer layer positioned on one side of the first flexible sheet body adjacent to the first flexible circuit layer, second flexible sheet body configured on one side of the spacer away from the first flexible circuit layer and second flexible circuit layer configured on one side of the second flexible sheet body adjacent to the spacer layer. Whereby, the present invention can achieve the contact and conduction anywhere to make the use thereof easier and more convenient.

The switch structure provided in a control device of a vehicle ceiling part comprises a cover that is openable and closable between a closed position to cover a switch and an opened position to open the switch, and in the cover, a region that covers an operation surface of an operation element of the switch in at least the closed position is formed of a member that transmits light, and the cover has a top surface comprising an inclined portion inclined at an upward gradient from a vehicle front toward a vehicle rear in the closed position.

The invention provides an input device, including: a substrate, including at least one connecting portion and at least one limiting portion; at least one key, including at least one first engagement portion and at least one second engagement portion located on two opposite sides, where the first engagement portion is in contact with the connecting portion, so that the key can rotate relative to the substrate by taking the connecting portion as a rotation center, and the second engagement portion faces the limiting portion and is spaced apart from the limiting portion; and a buffer unit, disposed on at least one of two surfaces of the limiting portion and the second engagement portion facing each other. By disposing the buffer unit, noise generated due to the collision between the second engagement portion and the limiting portion can be decreased.

The invention provides an input device including a holder, a first wheel, a slider, and a first pressure part. The first wheel is disposed on the holder, and includes a side surface, a circle center, and a segment adjusting structure. The segment adjusting structure is disposed on the side surface in a manner of surrounding the circle center. The slider is disposed on the holder, and is movable relative to the holder to move toward or away from the circle center. The first pressure part includes two first ends. One of the first ends is connected to the slider, and as the slider moves toward or away from the circle center, interference between the other first end and the segment adjusting structure is increased or reduced.

The present invention provides a touch device, including a cover plate, a circuit board, a bracket, and a noise reduction layer group. The circuit board is fixed below the cover plate. The circuit board is provided with a trigger zone located on a bottom surface, and includes an elastic sheet located in the trigger zone. The bracket is disposed below the circuit board. The noise reduction layer group is disposed between the bracket and the elastic sheet.
