A switch cap for a switch device that can reduce a pressing error of a switch is provided. A three-dimensional first cap main body moves by a force applied to a first abutting portion from a finger which is an operator. A first sensor is disposed in the first cap main body, and detects abutting or approach of the finger to the first abutting portion. A first transmission member is fixed to the inside of the first cap main body, and moves together with the first cap main body for first switching to transmit movement of the first cap main body to a push button which is a predetermined location of a switch device. A first sensor is formed in a flexible printed circuit board (FPC) disposed in the first cap main body, and the FPC is fixed by the first transmission member and the first cap main body.

The present disclosure provides a keycap, including: a light-guiding microstructure layer made of a first material, the light-guiding microstructure layer including a base layer and a plurality of microstructures disposed on a lower surface of the base layer; and a light-transmitting layer disposed over the light-guiding microstructure layer and in contact with the base layer, the light-transmitting layer being made of a second material different from the first material. The present disclosure further provides a method of manufacturing the above-mentioned keycap and a key structure including the above-mentioned keycap.

A keycap is provided, including a base element, a cap and a character element. The base element includes a board main portion. The cap has a top portion, and a skirt portion. The skirt portion surrounds the top portion. The character element, located between the board main portion and the top portion. An area of the top portion corresponding to the character element is a top area. The thickness of the top area is substantially greater than or equal to 0.01 cm and substantially less than or equal to 0.3 cm.

Various processes for creating mirrored features are discussed herein as well as devices that include the mirrored features. One embodiment includes a button having a transparent layer and an opaque layer coupled to the transparent layer. A portion of the transparent layer extends through the opaque layer so that the portion of the transparent layer is flush with a back surface of the opaque layer and generally has a shape of a desired feature. The button also includes a reflective object positioned so that it may be seen through the transparent layer.

A push switch includes a casing, an operation body movable into and out of the casing, and a switch element operable with the movement of the operation body into and out of the casing. The casing includes a first outer peripheral wall, a first inner peripheral wall, a first guide provided to the first outer peripheral wall, and a second guide provided to the first inner peripheral wall. The operation body includes a second outer peripheral wall, a second inner peripheral wall, a first engagement portion provided to the second outer peripheral wall and slidably engaged with the first guide, and a second engagement portion provided to the second inner peripheral wall and slidably engaged with the second guide. A clearance between the second guide and the second engagement portion is smaller than a clearance between the first guide and the first engagement portion.

The switch housing for capacitive switches has an outer contact surface and flat electrode structures which are arranged on the inside and in a position opposite the contact surface and which are placed by two-component injection molding in recessed regions of the housing body injected from a first, electrically non-conductive plastic component by a second, electrically conductive plastic component. Preferably, both plastic components are a polycarbonate, the second plastic component containing carbon fibers.

A keycap, an illuminating keyswitch and a method for manufacturing the same are provided. The illuminating keyswitch comprises a base plate, a printed circuit board, a light emitting element, a keycap and a lifting support structure. The printed circuit board is disposed on the base plate. The light emitting element electrically is connected to the printed circuit board. The keycap is disposed on the light emitting element. The lifting support structure is disposed between the base plate and the keycap. The keycap comprises a first injection layer and a second injection layer. The second injection layer covers the first injection layer. The light emitting element is configured to correspond to the first injection layer or the second injection layer. The keyswitch of the present invention covers the first injection layer through the second injection layer, so that the surface of the key cap is flat, thereby facilitating subsequent processing.

A keycap is provided, including a base element, a cap and a character element. The base element includes a board main portion. The cap has a top portion, and a skirt portion. The skirt portion surrounds the top portion. The character element, located between the board main portion and the top portion. An area of the top portion corresponding to the character element is a top area. The thickness of the top area is substantially greater than or equal to 0.01 cm and substantially less than or equal to 0.3 cm.

A light-emitting assembly positioned within a switch housing of a keyboard assembly for an electronic device is disclosed. The light-emitting assembly may include a phosphor structure, a transparent material positioned on opposing side surfaces of the phosphor structure, and an epoxy layer formed over an entire back surface of the phosphor structure and the transparent material. The light-emitting assembly may also include a mask layer formed over an entire top surface of: the phosphor structure, the transparent material, and the epoxy layer. The light-emitting assembly may further include a light source positioned within the phosphor structure for emitting a light.

A waterproof keyboard structure and an assembly method thereof are provided. The waterproof keyboard structure includes a keyboard module, and a keyboard frame framing on the keyboard module, wherein an elastic waterproof layer is formed by means of double injection or insert molding on the keyboard frame. The keyboard module is defined with a key surface, and an assembly surface arranged opposite to the key surface. The elastic waterproof layer is clad on the key surface, and the keyboard module with the assembly surface facing a seat is assembled together with the keyboard frame in an accommodating space, thereby having the elastic waterproof layer closely fit with the seat to form a waterproof ring.
