An electronic push button for a motor vehicle door handle, including an activation pattern supported by a membrane that is flexible in the direction of an electric switch carried by a printed circuit board, the activation pattern defining an activation surface that is pressed by an operator's finger in order to push the activation pattern in the direction of the electric switch. The activation pattern is made up of a set of studs that extend parallel to one another away from the electric switch, with the majority of the studs being spaced apart from one another, the set of studs discontinuously delimiting an outer contour of the activation surface of the electronic push button.

The present invention disclosed an elastic body for keyswitch assembly, comprising a body and identification marks. The body has an annular base and an elastic pressing part, and the elastic pressing part is disposed on the annular base. The identification marks are disposed on the side of the annular base. Therefore, the mold producing poor elastic body and cavities on it can be identified by the identification marks on the elastic body, so damaged cavities can be repaired quickly and effectively then. The location and means of marking of the identification marks does not affect the adhesion of the elastic body to the prefabricated thin film circuit board. The present invention further provides a keyswitch assembly comprising the elastic body of the present invention.

A keycap forming method includes the following steps. Firstly, a stabilizer bar is formed through a first male mold and a first female mold according to an injection molding process, and a keycap is formed through a second male mold and a second female mold according to the injection molding process. Then, the stabilizer bar is fixed on the first male mold, and the keycap is fixed on the second female mold. Then, the first male mold and the second female mold are stacked on each other, so that the stabilizer bar and the keycap are combined together. Then, the first male mold and the second female mold are separated from each other, so that the stabilizer bar is detached from the first male mold. By using the keycap forming method, it is not necessary to manually assemble the stabilizer bar with the keycap.

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.

A luminous keycap includes a base made of a light-transmitting material and a transparent cover, wherein the base is provided with a first light-shielding layer and the top surface thereof is provided with a first light-transmitting area, and the inner surface of the cover is provided with a second light-shielding layer. The surface of the second light-shielding layer directly opposite to the first light-transmitting area is engraved with a second light-transmitting area. The cover is correspondingly fixed onto the base. The method of manufacturing the same is also described. The keycap and the manufacturing method thereof achieve the goal that its user can accurately and swiftly use the keyboard in a dark environment. It solves the problem that the user often touches characters and/or patterns so often that they are worn away. It has a better touch, and the keycaps have a longer lifetime.

A keycap for a luminous keyboard comprises a base and a cap made of a transparent material. The base is provided with a first stage, and the top surface thereof is transparent. The cap covers the first stage, and is fixedly connected with the base. The cap is provided with a light-shielding layer, and the surface of which and opposite to the first stage is engraved with a light-transmitting area by laser. A manufacturing method for the same is described. Using the disclosed keycap and the manufacturing method thereof, the operator can accurately and quickly operate the keyboard in a dark environment, making the usage more convenient. As the light-transmitting area in the shape of characters or patterns is not likely to be rubbed or erased, the lifetime of the keycap is prolonged.

The present invention provides a key cap structure comprising a first key and a light transmissive body and a second key. At a side of the first key is formed with a bearing bevel and a side opening. The light transmissive body is disposed on the bearing bevel, the second key is disposed on the light transmissive body, and the first key and the light transmissive body and the second key are formed with different materials by injection molding. In this way, dissimilar materials of the key cap structure can be distinguished by colors or transparently, thereby achieving the efficacies of a variety of various materials and lighting effects.

A symbol button for a vehicle includes: a button body; a button surface portion positioned at an upper portion of the button body; a symbol printing portion positioned on the button surface portion; an anti-plating portion positioned at a lower portion of the button body; and a metal plating layer positioned at the outside of a button excluding the symbol printing portion and the anti-plating portion.

A resin structure includes a molded resin element and a push-type switch. The push-type switch includes a receptacle whereon a first terminal and a second terminal are secured, the first terminal and the second terminal configured to connect to an electrical circuit; a button unit protruding from the receptacle; and a contact spring unit configured to move with the button unit, to electrically connect between the first terminal and the second terminal, and to generate an opposing force relative to a pressure applied between the receptacle and the button unit. The receptacle stores the button unit and the contact spring unit. The receptacle of the push-type switch is embedded in the molded resin element with the button unit exposed from the molded resin element.

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.
