A key structure includes a key cap, a bridge assembly, a first supporting part, a second supporting part, an attractable element and a magnet. The bridge assembly includes first and second hinge parts. One end of the first hinge part has a first link bar, and the other end has a first pivot coupling portion and a first shaft having a first connecting portion. One end of the second hinge part has a second link bar, and the other end has a second pivot coupling portion and a second shaft having a second connecting portion coupled to the first connecting portion. When the magnet under a first attractive position, the first end of the attractable element is attracted to the first attractive position. When the magnet under a second attractive position, the second end of the attractable element is attracted to the second attractive position.

A keyboard device includes plural keycaps and a membrane switch circuit member. The membrane switch circuit member is disposed under the plural keycaps. The membrane switch circuit member includes a wiring board and plural separate covering pads. The wiring board includes plural first trace patterns and plural second trace patterns corresponding to the plural keycaps. The plural second trace patterns are disposed on the wiring board and separated from the plural first trace patterns. There is a gap between each first trace pattern and the adjacent second trace pattern. The covering pads are disposed over the wiring board. The plural covering pads are aligned with the corresponding keycaps and cover the corresponding gaps. The covering pad has a triggering trace pattern over the corresponding gap.

A switch assembly for adapting a non-contact switch into a contact triggered switch, such that the internal electrical state of the non-contact switch can be triggered by mechanical contact with an object or surface. The switch assembly can include an adapter body coupled to the non-contact switch and an actuation body coupled to the adapter body. The actuation body can be movable relative to the adapter body to selectively position a target supported by the actuation body within a sensing region of the non-contact switch. The actuation body can be moved by an external object making contact with a portion of the actuation body.

A keyboard device includes plural key structures. Each key structure includes a base plate, a keycap, a connecting member and at least one raised structure. The keycap is located over the base plate. The connecting member is arranged between the base plate and the keycap. The keycap is movable upwardly or downwardly relative to the base plate through the connecting member. The connecting member includes at least one first hook part. The raised structure is installed on the base plate. The first hook part is connected with the raised structure. The raised structure includes a top wall, a lateral wall and a perforation. The lateral wall is connected between the top wall and the base plate. The perforation is formed in the lateral wall. The first hook part is penetrated through the perforation and contacted with the top wall.

A keyswitch includes a base plate, a cap having a longitudinal axis, a returning device, a support mechanism, and a lifting mechanism including first and second support plates. The first support plate has first and second edges parallel to the longitudinal axis for respectively abutting against the base plate and the cap. The second support plate has third and fourth edges parallel to the longitudinal axis for respectively abutting against the base plate and the cap. The base plate is disposed through openings of the first and second support plates to make the first and second support plates movably connected to the base plate. The returning device drives the cap to a non-pressed position with rotation of the first and second support plates. The support mechanism has first and second support members pivoted to each other to be movably connected to the cap and the base plate.

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.

A hair straightener and its integrated switch for control and display are disclosed. The hair straightener comprises first and second clamping plate parts and the integrated switch for control and display arranged on an inner side of the second clamping plate part. The integrated switch for control and display comprises a temperature control knob assembly for regulating and controlling temperature, a display button assembly for displaying the temperature and turning on or off a power supply, and a control motherboard for digital display and electrical control. The temperature control knob assembly and the display button assembly are installed on the control motherboard. The temperature display, control and regulation functions, and the power supply switching on and off functions are centralized on the same switch key, such that the temperature can be controlled and regulated conveniently when operated by one hand and the visual information can be obtained without obstacles.
