A push button for a control panel. The push button includes a button body and a reflector molded as a single, monolithic piece with links extending between the button body and the reflector. A divider of the button body is between a first light source of a printed circuit board and an indicator light guide of the button body. The divider restricts light from the first light source from illuminating the indicator light guide.

The present invention discloses a film structure for a keycap, including a molding film presenting a shape conforming with the outline of the upper surface outline of the keycap; and a polyurethane (PU) layer disposing on the molding film and engraved a symbol thereon, wherein the symbol indicates a specific keycap. In the present invention, the problems with the symbols of the keycaps becoming dislocated, yellowed and deformed when the keycaps are manufactured with currently available techniques can be overcome, and users can clearly see the symbols on a backlit keyboard.

The present invention discloses a keycap for keys of a keyboard device, wherein the keys are configured on the keyboard, and the keycap is configured on a key body. The keycap includes: a top fabric layer, a keycap body including an upper surface outline, and a molding film. The top fabric layer is used for engraving to have a symbol thereon to transmit light therethrough, wherein each symbol indicates a specific keycap. The molding film is disposed between the top fabric layer and the keycap body to render the top fabric layer in a specific shape matching with the upper surface outline. In the present invention, the problems with the symbols of the keycaps becoming dislocated, yellowed and deformed when the keycaps are manufactured with currently available techniques can be overcome, and users can clearly see the symbols on a backlit keyboard.

The present invention discloses a method to manufacture a keycap for keys of a keyboard, including: providing a top fabric layer and a molding film disposed beneath the top fabric layer; molding the molding film and the top fabric layer to form a film structure having an inner surface; and providing a keycap body having an upper surface, wherein the outline of the upper surface matches with that of the inner surface to form the keycap. In the present invention, the keycap is formed using the film structure and the keycap body by plastic injection or adhesion agent, the keycap is further manufactured as keys, and a symbol is engraved on the upper surface of the film structure by laser. Because the backlit device's light transmits through the keycap, users can recognize the symbols on the keys.

Provided is a soft upper trim of a vehicle door, in which an upper substrate, foam, and a transparent skin are laminated, and particularly, to a soft upper trim for switch assembly of a vehicle door, in which a switch, which is configured to preserve continuity of a transparent skin and display lock and unlock symbols on the transparent skin, is easily assembled to an upper substrate, and a method of manufacturing the same.

An electric circuit breaker device with a reduced size. A first through hole 22a of a cut portion 20 and a first attachment hole 43 of a first connection portion 40 are placed on a first fixing pin 35 of a projectile 30, and a second through hole 23a of the cut portion 20 and a second attachment hole 48 of a second connection portion 45 are placed on a second fixing pin 36. By deforming an end portion of the first fixing pin 35 and an end portion of the second fixing pin 36, the projectile 30, the cut portion 20, the first connection portion 40, and the second connection portion 45 can be integrally formed together.

A keyboard includes a plurality of key modules. Each key module includes a baseplate, a circuit membrane disposed on the baseplate, a metal dome disposed on the circuit membrane, an elastic member disposed on the metal dome, and a keycap. The elastic member and the linkage member are configured to be a movable switch mechanism. The circuit membrane has a conductive circuit. The metal dome has an opening corresponding to the conductive circuit of the circuit membrane. A trigger portion protrudes from an underside of the elastic member. When the keycap is pressed, the trigger portion passes through the opening of the metal dome, and moves downwards to abut against the conductive circuit to induce a conducting signal. The movable switch mechanism can be made by a double injection molding method.

A reinforcement structure for a vacuum interrupter is disclosed. For example, in some implementations, a vacuum interrupter includes a first electrical contact; a second electrical contact; a vessel that encloses the first electrical contact and the second electrical contact in an evacuated space, the vessel including an endcap; and a reinforcement structure at an exterior surface of the endcap, the reinforcement structure including a first side, a second side, and an opening that passes through the reinforcement structure from the first side to the second side. The exterior surface of the endcap includes a recessed region, and at least a portion of the opening is positioned over the recessed region.

Provided is a soft upper trim of a vehicle door, in which an upper substrate, a foam, and a transparent skin are laminated, and particularly, to a soft upper trim for switch assembly of a vehicle door, in which a switch, which is configured to preserve continuity of a transparent skin and display lock and unlock symbols on the transparent skin, is easily assembled to an upper substrate, and a method of manufacturing the same.
