A wireless switch includes a cover member, a button member, a first plunger, a second plunger, a trigger spring, a return spring, a shaft, a housing, and a power generation module. An intermediate member constituted of the first plunger, the second plunger, the trigger spring, the return spring, and the shaft is connected between the button member and the power generation module. The intermediate member prevents a position of the shaft making contact with the power generating shaft of the power generation module from changing, and causes stress to build up in the trigger spring, until a movement distance of the button member reaches a predetermined distance. The intermediate member releases the stress built up in the trigger spring and pushes the power generation shaft with the shaft using the released stress upon the movement distance of the button member reaching the predetermined distance.

A wireless switch includes a button member, a power generation module, an RF module, and a notification unit. The button member is mounted in a housing, and is configured to move. The power generation module is configured to generate power using energy produced by the movement of the button member. The RF module is connected to the power generation module, and is configured to transmit a switch signal using power generated by the power generation module. The notification unit is configured to operate using power generated by the power generation module. The RF module controls the notification unit in one or more notification states according to a strength or details of a reception state signal corresponding to the transmitted switch signal.

In some implementations, a key structure may include a lower shell fixedly connected to a keyboard base. In addition, the device may include an upper shell assembled above the lower shell, where the upper shell is made of transparent plastic material, the upper shell is provided with having a through opening. The device may include a plurality of light guide columns extending downwardly from two sides of the bottom of the upper shell, where the plurality of light guide columns and the plurality of light-emitting sources are arranged opposite to each other. Moreover, the device may include a pressing shaft movably disposed between the lower shell and the upper shell, where a top end of the pressing shaft penetrates through the opening. Also, the device may include a spring disposed and elastically supported between the lower shell and the pressing shaft.

A game machine input device mounted on a game machine provided with a playfield; the game machine input device includes: an input unit provided toward the front of the playfield and configured to accept input; and a projection part configured to radiate light toward the playfield to project a first image in a region within the visual field of a player viewing the playfield.

A switch for a power tool, the switch including a printed circuit board and a silicone layer. The printed circuit board has a first microswitch, while the silicone layer has a blocking switch, the silicone layer being present arranged on the printed circuit board such that an actuation of the blocking switch leads to an actuation of the first microswitch. Furthermore, the printed circuit board can have a second microswitch, and the silicone layer can have a membrane, an actuation of the membrane leading to an actuation of the second microswitch. A method for switching on a power tool, the power tool including a switch having a printed circuit board and a silicone layer. An ergonomically advantageous switch is also provided, which switch is furthermore well protected against dust, dirt and/or water and enables inadvertent switching on of the power tool to be effectively avoided.

An input device includes an exterior member having an opening formed therein; an input member that has an upper surface to be touched by a user with a finger and that is disposed inside the opening; and a light diffusing member having a light emitting surface located along an outer edge of the input member, where the light emitting surface has a first region exposed in a gap between an inner edge of the opening of the exterior member and an outer edge of the input member and a second region positioned on an inner side of the outer edge of the input member and below a peripheral portion of the input member.

A light-transmissible keycap and the manufacturing method thereof are provided. The light-transmissible keycap has multiple light-transmissible symbol areas, and each light-transmissible symbol area has at least one character assigned with a color. Each light-transmissible symbol area is covered with only one light-transmissible color layer. Thus, when an external light is emitted from a light source beneath the keycap, the external light will only pass through one light-transmissible color layer covering that light-transmissible symbol area, and not pass through the light-transmissible color layer covering the other light-transmissible symbol area. Therefore, a bleeding problem due to multiple light-transmissible color layers overlapped and covering the same light-transmissible symbol area is avoided.

A key structure includes a base, an elastic member disposed on the base, a scissors structure movably disposed on the base, and a keycap module having a carrier and a light source. The carrier is detachably assembled to the scissors structure and abuts the elastic member. The light source is disposed in the carrier. The light source is electrically connected to a bottom portion of the base through a flexible circuit member penetrating the carrier, passing the scissors structure, and penetrating the base. A top portion of the carrier has light transmittance, so that light of the light source can pass through the top portion to be projected from the key structure.

A multi-illuminated pushbutton, including a substrate having a switch and a button cap. A lighting board may be affixed to the substrate, the lighting board having a first light source, a second light source, and a through channel disposed between the first light source and the second light source. The button cap can have a first window for transmission of light from the first light source, a second window for transmission of light from the second light source, and a button base disposed through the channel of the lighting board and in operable relation with the switch. The button base can be shaped to prevent substantially all light emitted from the first light source from transmission through the second window and prevents substantially all light emitted from the second light source from transmission through the first window.

An illuminated keyswitch structure includes a base plate, a keycap, and a light-emitting die package. The light-emitting die package is disposed to illuminate the keycap through the base plate. The light-emitting die package comprises a warm color temperature light-emitting die and a cold color temperature light-emitting die, and the light-emitting die package extends along an arrangement direction. Each of the two light-emitting dies has a short side arranged adjacent to each other, with a long side of each of the two light-emitting dies facing a same direction and configured proximate to each other. A gap between the two adjacent short sides of the two light-emitting dies is not greater than either one of the two adjacent short sides of the two light-emitting dies.
