A push-button on a device includes a shell of the device, an internal locking portion to connect with the device, a touch pole far away from the locking portion, and a supporting flange portion extending from the internal surface of the shell. The supporting flange portion and the device support each other. When the shell is pressed, the push-button elastically deforms as the locking portion 103 acts as a fixing point and the supporting end acts as a supporting point. The touch pole moves with the shell and the switch on a PCB is triggered to generate at least one signal.

A light emission module and a light guide plate and a manufacturing method thereof are provided. The light guide plate is configured to guide the light received and has a first lateral surface and a tongue extending from the first lateral surface toward a light source. The tongue has a flat end surface that faces or engages with the light source. The light guide plate receives the light emitted from the light source by the flat end surface, so as to reduce or eliminate the gap between the light source and the light guide plate. Therefore, the loss of light energy during the light traveling in air is effectively reduced, and the intensity of light received by the light guide plate from the light source meets expectation, improving the lighting effect of the light emission module.

A display switch includes a holding portion that formed by a light guide member and adapted to hold a held portion, and a display portion that is integrally formed with the holding portion by the light guide member, is embedded in a light shielding portion, and emits light by guiding a light irradiated to the holding portion.

A seamless button including a guiding element, a movable actuating element and a switch located on a mounting plate. The movable actuating element is made of elastic material with a massive middle shaft spaced from the inner walls of the chamber by an air gap. It has an upper actuating surface and crimp surrounding the actuating surface above the air gap. It also has a profile area at the outer circumference of the movement crimp, where the horizontally outwardly extending portion of the profile area rests on top of the outer wall, the downwardly extending portion of the profile area rests on the outside of the outer profile edge and the protrusion rests on the pedestal covering it at least partially. A seamless multi-button is also disclosed, with a method for manufacturing seamless buttons.

A button structure includes a circuit board, a switch module, a light source module, and a button body. The button body includes a substantially cylindrical shaped light guide member and a pressing member. The light guide member includes a periphery wall having at least one light guide surface. The pressing member is movably mounted in the light guide member and faces the switch module. When the pressing member is pressed, the pressing member activates the switch module and the switch module is activated to control the light source module to irradiate light, so that the light from the light source module enters the light guide member through the at least one light guide surface and is emitted out from a top portion of the periphery wall.

An illumination display switching device includes a switch knob slidable with respect to a push button-type switch. The switch knob includes a display operation part including a display design and a non-display design, a lock arm that is vertically hung from a central portion of the display operation part and connected to the push button-type switch, a light guide member that is vertically hung from the display operation part positioned near the light source, and an interconnection light guide member that interconnects the light guide member, a base of the lock arm and the display design. The display design is illuminated from a backside by emission light of the light source through the light guide member and the interconnection light guide member. The lock arm, the light guide member and the interconnection light guide member are integrally molded with the display design by the light-transmitting resin.

A luminous keyboard includes a keypad module, plural light-emitting elements, a light guide plate and a reflecting plate. The reflecting plate has plural light amount control structures. The light amount control structures are disposed on the reflecting plate, and located near the corresponding light-emitting elements. When the plural light-emitting elements emit light beams, the portions of the light beams that are not subjected to total internal reflection within the light guide plate are reflected by the reflecting plate. When the light beams are transferred through the light amount control structure, the reflected fraction of the light beams is reduced. Since the light beams are not very centralized, the problem of generating bright spots will be diminished.

A backlight keyswitch includes a keyswitch body, a board connected to the keyswitch body, a backlight module and a membrane disposed between the keyswitch body and the board. The backlight module is disposed under the board and includes a backlight circuit board, a light-blocking sheet, a first reflecting ink layer, and a light guide plate disposed between the light-blocking sheet and the backlight circuit board. The first reflecting ink layer is formed on the light-blocking sheet and located above the backlight circuit board, for at least partially reflecting light emitted by the backlight circuit board back to an optical microstructure in the light guide plate to prevent center symbols of the keyswitch body from being too bright, such that light can be incident to the keyswitch body via scattering of the optical microstructure to increase brightness of side symbols of the keyswitch body.

A light-emitting keyboard includes a bracket, keycaps, a circuit layer, a composite light-emitting layer, a spacing layer and an adhesive layer. The keycaps are disposed on the bracket and connected to the bracket. The circuit layer is disposed between the keycaps and the bracket. The composite light-emitting layer is disposed under the bracket, and includes a conductive layer, and light sources. The light sources are electrically connected to a portion of the conductive layer. The spacing layer is disposed between the composite light-emitting layer and the bracket, and includes holes corresponding to the light sources. One of the light sources is located in one of the holes of the spacing layer, and the light source is spaced from a wall of the corresponding hole. The adhesive layer is disposed between the composite light-emitting layer and the bracket, and the adhesive layer is spaced from one of the light sources.

Systems, methods, and apparatus for a junction box assembly are described. A junction box assembly can include or contain devices and components, such as any of the following: a junction box having an interior for containing any of devices and components included in the junction box assembly; a base plate having a central opening and a periphery attaching to the junction box; a grounding wire attached to the base plate; a device connected to the grounding wire and disposed in the central opening of the base plate; a button array having any number of buttons and attaching to the device; and a face plate disposed to attach to the base plate and to surround the button array.
