    摘要： A method is provided for producing a graphic for a backlit component, such as a button for an illuminated graphic display of an automobile instrument panel. The method involves a process by which molded plastic backlit buttons are manufactured without the use of hazardous chemicals or materials, and instead utilizes laser energy to produce substantially opaque regions on the button for forming a graphics image. Backlit buttons are preferably formed from a substantially transparent polymeric material in which is present pigmentation that is reactive to laser energy. A graphic image is then created on the button by selectively exposing a portion of the backlit component to laser energy. As a result, the exposed portion becomes substantially opaque while remaining portions of the backlit component remain substantially transparent. As such, the exposed and unexposed portions of the button cooperate to produce the graphic image when the button is backlit with a suitable light source.

    摘要翻译： 提供了一种用于产生用于背光组件的图形的方法，例如用于汽车仪表板的照明图形显示的按钮。 该方法包括在不使用危险化学品或材料的情况下制造模制塑料背光按钮的过程，而是使用激光能量在按钮上产生基本上不透明的区域以形成图形图像。 背光按钮优选由基本上透明的聚合物材料形成，其中存在着与激光能量无关的色素沉着。 然后通过将背光组件的一部分选择性地暴露于激光能量来在按钮上创建图形图像。 结果，暴露部分变得基本上是不透明的，而背光部件的剩余部分保持基本上透明。 因此，当按钮用合适的光源进行背光照亮时，按钮的曝光和未曝光部分合作产生图形图像。

    摘要： A pushbutton for an automotive control panel has a button portion extending through a hole in a trim plate and an enlarged skirt portion behind the plate, and is spring loaded to push the skirt against the rear surface of the plate. A ledge surrounding the button opposes the rear surface. The pushbutton is painted and paint on the ledge causes the skirt to stick to the rear surface of the plate. To prevent sticking, pointed spacers are molded on the ledge so that only the spacer points engage the plate. Sticking from paint adhesion is minimized due to the small amount of paint on the spacer points. Alternatively, the pointed spacers are formed on the rear surface of the plate.

    摘要翻译： 用于汽车控制面板的按钮具有延伸穿过装饰板中的孔的按钮部分和板后面的扩大的裙部，并且弹簧加载以将裙部推靠在板的后表面上。 围绕按钮的凸缘与后表面相反。 按钮被涂漆，凸台上的油漆使裙子粘在板的后表面上。 为了防止粘附，尖锐的间隔件被模制在凸缘上，使得只有间隔件接合板。 由于涂层附着力少，因为间隔点上的油漆量少。 或者，尖锐的间隔件形成在板的后表面上。
