A switch structure includes a light-emitting part configured to receive power from a vehicle and to radiate light, a moving block located so as to surround the light-emitting part, a light-transmissive part configured to allow light radiated from the light-emitting part to pass through an opening in the moving block, and a film-printing layer located on a top surface of the light-transmissive part and including a symbol.

A waterproof film includes a film reinforcing layer, a light shielding layer, a texture layer, and a pattern. The light shielding layer is combined under the film reinforcing layer and forms a plurality of protruding structures cooperatively with the film reinforcing layer by a hot pressing process. The texture layer is attached to a release film and then formed on a top surface and a side surface of each protruding structure after a hot pressing process is performed and the release film is then peeled. The pattern is formed on the texture layer or the light shielding layer.

An illumination switch device includes a push button, a plurality of indicator lenses, a holder, a detector, a plurality of light emitters, and a base. The push button has an internal space and an opening. Each indicator lens has a columnar shape. The indicator lenses are juxtaposed in the internal space of the push button. The holder holds the push button such that the push button is movable in a longitudinal direction of each indicator lens. The detector detects a displacement of the push button in the longitudinal direction. The light emitters are respectively disposed opposite one ends of the indicator lenses in the longitudinal direction. The base is made of an opaque resin, and covers side faces of the indicator lenses while being in tight contact with the side faces. The base is integrated with the indicator lenses.

A switch including a waterproof and light leak prevention structure is disclosed. The switch according to an embodiment of the present invention is a switch including a light emitting member and a push switch on a mount, and includes a switch including a cover plate provided on the mount and configured to cover the light emitting member and the push switch, and the cover plate comprises includes a rubber dome disposed at a position corresponding to the push switch, a light emitting member cover configured to cover the light emitting member at a predetermined distance from an upper surface of the light emitting member, and a light leak prevention protrusion configured to surround a periphery of the light emitting member and to extend upward up to a predetermined height.

A keyboard device includes plural key structures, a membrane circuit board and a flexible light shielding element. Each key structure includes a keycap. The keycap has a first end surface and a second end surface. The membrane circuit board is located under the keycap. The flexible light shielding element is arranged between the keycap and the membrane circuit board, and includes a bottom layer and plural stopping walls. Each stopping wall includes a wall body and a platform part. The wall body is protruded from the bottom layer and in the direction toward the keycap. An included angle is formed between the wall body and the bottom layer. The platform part is protruded from the wall body. The platform part is arranged between the second end surface of the keycap and the bottom layer. The platform part is contacted with the second end surface.

A keyboard includes a base plate, a membrane circuit board, a backlight module, and a plurality of keyswitch assemblies. The base plate has a plurality of through holes. The membrane circuit board is disposed on the base plate. The backlight module is disposed at a side of the base plate away from the membrane circuit board and configured to emit light toward the base plate. The keyswitch assemblies are disposed on the membrane circuit board. Each of the keyswitch assemblies includes a position-returning member located over one of the through holes. An orthogonal projection of the position-returning member projected on the base plate overlaps a part of said one of the through holes.

A switch used in an operation device such as a mouse has flexibility, and includes a movable member in which a first end side is fixed as a swing fulcrum and a second end side swings, and a pressing member that presses a portion between the first end and the second end of the movable member by receiving a pressing force from an outside source. Bent portions that are bent in a swinging direction are formed in side portions of the movable member. When the movable member warps by being pressed by the pressing member, the bent portions resist against the warping of the movable member, and therefore an operator can have click feeling.

A keyboard having multiple layouts includes depressible keys. A light reflector is positioned under at least some of the depressible keys with light sources configured to emit light towards the light reflectors. The light impinges on one of a plurality of reflective surfaces of the light reflectors and is reflected towards a corresponding depressible key under which the light reflector is positioned to cause a character or symbol to appear on a surface of the depressible keys. A switch allows a user to selectively control the character or symbol appearing on the surfaces of the depressible keys, resulting in more efficient input for the multiple layouts that improves the user experience.

Provided is a key structure including a base plate having at least one connecting seat and at least one notch adjacent to a lower portion of the connecting seat; a keycap disposed above the base plate in a liftable manner; a thin film circuit assembly disposed on the base plate and located between the base plate and the keycap; and a supporting rod connected to the keycap and the base plate and located between the thin film circuit assembly and the keycap. An accommodating space formed by the notch extends from and communicates with a through hole of the connecting seat. The connecting seat protrudes out from an opening of the thin film circuit assembly. A vertical projection region of the notch on the base plate is located within a vertical projection region of the opening on the base plate. The invention also provides a keyboard module.

A keyboard module including keys, a frame, a bottom plate, and a backlight assembly is provided. The frame has a key region. Top surfaces of the keys are exposed in the key region. The frame includes a column. The bottom plate is disposed under the frame. The bottom plate includes a bending portion. The backlight assembly is disposed under the bottom plate, and sequentially includes a light shielding sheet, a light guide plate, and a reflector. The light shielding sheet has a first opening. The light guide plate has a second opening. A part of the reflector is exposed by the first opening and the second opening. The column passes through the bending portion and is located in the first opening and the second opening. A bottom surface of the column leans against the reflector.
