A panel-type control button, including: a press key base, a press key panel, a switch board and a springback soft key. The press key panel is snap-fitted on top of the press key base, and one end of the press key panel is rotatably mounted at one end of the press key base. The switch board is located below the press key base, and is provided thereon with a switch mechanism. The springback soft key is located above the switch mechanism of the switch board. When the press key panel is pressed, the press key panel comes into contact with the springback soft key and triggers the switch mechanism on the switch board, and further controls the opening and closing of the switch mechanism. The springback soft key provides a springback force for the press key panel to reset.

The present invention provides a luminous keyboard, including a key, a ring-shaped shading element, and a light source. The ring-shaped shading element is disposed between the key and the light source and is configured to shade light generated by the light source. When the key is pressed down, the key presses down the ring-shaped shading element and enables the ring-shaped shading element to be deformed, so as to prevent the ring-shaped shading element from affecting strokes of the key.

A switch device includes a casing that includes a recessed bearing portion, a rotatable drive member that includes a shaft portion disposed in the bearing portion, a switch driven by the drive member, and a covering member that includes a pressing structure provided so as to press an upper portion of the shaft portion and that is secured to the casing. The covering member includes an operating portion that faces the drive member such that the operating portion is able to press the drive member and that is formed of an elastically deformable elastic material and a base portion that is secured to the casing, that is formed of a synthetic resin material, and that is integrated with the operating portion. The pressing structure is integrated with the base portion and formed of an elastically deformable elastic material.

A keyboard includes a base board; transversely moveable boards, each moveably provided on the base board and including a film circuit board, a resilient dome on the film circuit board, a hole member on the film circuit board and adjacent to the resilient dome, openings on the film circuit board, a hollow structure in the film circuit board and directly under the resilient dome, a top contact in the hollow structure, and a bottom contact in the hollow structure and spaced from the top contact; key caps; and scissors-type bridge structures, each including a first frame member, a hollow, rectangular second frame member, and a peg extending out of the first frame member. Top of the scissors-type bridge structure is pivotably secured to the key cap. Bottom of the scissors-type bridge structure is pivotably secured to the base board by inserting through the holes onto the base board.

A key switch includes a baseplate, a circuit layer, a keycap and a support rod. The baseplate has a hook and a first through hole neighboring to the hook. The circuit layer includes a first sublayer disposed above the baseplate and having a second through hole, and a second sublayer disposed above the first sublayer and having a third through hole; a portion of the second sublayer extends over the second through hole and forms a first resilient portion; the first resilient portion has four sides, two of which connect to the second sublayer; and the first resilient portion is neighboring to the hook. The keycap is disposed above the baseplate and can move upward and downward in respect to the baseplate. The support rod has a first portion and a second portion; the first portion movably connects to the keycap and the second portion engages the hook.

Embodiments describing a method of forming a multi-layered keycap structure are disclosed herein. The method includes forming a first polymer layer on a second polymer layer, wherein the first polymer layer includes a first color and the second polymer layer includes a second color, and coupling the first polymer layer and second polymer layer to a substrate layer such that the first polymer layer is closer to the substrate than the second polymer layer. The method may further include forming a third polymer layer on the second polymer layer; and etching the multi-layered keycap structure to form an opening having a bottom surface that exposes at least one of the first or second color.

The present invention relates to a protecting cover which covers a plurality of key caps of a keyboard. The protecting cover includes a connection pad and a plurality of cover bodies, where the connection pad is provided on a bottom plate of the keyboard. The cover body is provided on the connection pad and is covered at the corresponding key cap. The cover body includes an upper cover portion and a side wall portion. The upper cover portion covers an upper surface of the key cap, and the side wall portion surrounds the upper cover portion and covers a side edge of the key cap. Thickness of the side wall portion is smaller than thickness of the key cap, so that the side wall portion may be merely slightly deformed, so as to reduce a degree for the side wall portion to be squeezed.

A keyswitch device includes a bottom plate, a membrane circuit board, a keyswitch assembly, and at least one spacer structure. The membrane circuit board is located over the bottom plate and has a trigger zone. The membrane circuit board is configured to generate a trigger signal when the trigger zone is pressed. The keyswitch assembly is disposed over the membrane circuit board and configured to press the trigger zone. The spacer structure is disposed between the bottom plate and the membrane circuit board and substantially aligned with the peripheral edge of the trigger zone. The spacer structure is configured to separate the bottom plate and the membrane circuit board by a distance.
