技术领域technical field
本发明涉及薄膜技术领域，尤其涉及一种薄膜开关。The invention relates to the technical field of membranes, in particular to a membrane switch.
背景技术Background technique
薄膜开关由于体积轻薄，因此近年来被广泛地应用于各种电子产品，尤其薄膜开关于按压时所产生的声响极小，尤适用于各种装置的按键或键盘。传统的薄膜开关通常具有上下两层薄膜，且上下两层薄膜各具有一个或多个导电体，当使用者施力使上下两层薄膜相互靠近时，则上下两层的薄膜的导电体将会互相接触进而电性导通。然而，现今的薄膜开关很少具备供光特性，使得操作者操作不便，同时，按压位置的精确度也亟待改进；现有的薄膜开关不少采用三层式结构，包括上层线路板、绝缘层和下层线路板，其中上层线路板和下层线路板包括基材和印刷银线电路，上层线路板与绝缘层、绝缘层与下层线路板之间通过胶贴合，其生产工艺包括上层和下层印刷银线、跳线、胶合，生产工序较多，成本较高，且印刷银线时线路的不良率很高，防水能力较差。Membrane switches have been widely used in various electronic products in recent years due to their light and thin volume. In particular, membrane switches produce very little sound when pressed, and are especially suitable for buttons or keyboards of various devices. A traditional membrane switch usually has an upper and lower film, and each of the upper and lower films has one or more conductors. When the user applies force to make the upper and lower films approach each other, the conductors of the upper and lower films will are in contact with each other for electrical conduction. However, today's membrane switches seldom have light supply characteristics, which makes it inconvenient for the operator to operate. At the same time, the accuracy of the pressing position needs to be improved urgently; many existing membrane switches adopt a three-layer structure, including the upper circuit board, insulating layer and the lower circuit board, wherein the upper circuit board and the lower circuit board include substrates and printed silver wire circuits, the upper circuit board and the insulating layer, and the insulating layer and the lower circuit board are glued together, and the production process includes upper and lower printing Silver wires, jumper wires, and gluing have many production processes and high costs. In addition, when printing silver wires, the line defect rate is high and the waterproof ability is poor.
