Background technique

Problems with existing contact membrane switches:

The existing ultra-thin contact membrane switch is composed of two films printed with electronic circuits and metal contacts and a separator film. The metal contacts of the two electronic circuits are printed on the film by silver paste to form a thin film. The silver paste metal contact formed by the silver paste has a through hole on the isolation film, and the isolation film is located in two electronic circuits and respectively bonded to two electronic circuits, and the two electronic circuits are composed of an upper electronic circuit and a lower electronic circuit. The silver paste metal contact of the upper electronic circuit, the silver metal contact of the lower electronic circuit, and the through hole position on the isolation film correspond to the silver paste metal contact and the layer electronic circuit of the upper electronic circuit under the action of external force during use. The silver paste metal contact contacts the through hole in the isolation film, the switch is turned on, and the silver metal contact of the upper layer electronic circuit is removed, and the switch is disconnected.

The metal contacts of the existing contact type membrane switch are easy to be oxidized, easy to wear, and have a short service life, especially when the silver metal contact of the upper electronic circuit has a small side displacement when it contacts the silver metal contact of the layer electronic circuit. The side displacement accelerates the failure of the existing contact type membrane switch, and when used frequently, the formation of a silver metal contact oxidation---wear---reoxidation---grinding cycle causes the existing The contact membrane switch has a short life; in the absence of ultra-thin thickness requirements and high quality requirements, the existing high-quality contact membrane keyboard switches use micro-mechanical switches (metal contacts are welded with precious metal materials that are not easily oxidized) On the switch mechanism, the existing high-quality PC keyboards use hundreds of mechanical switches (metal contacts are welded to the switching mechanism with precious metal materials that are not easily oxidized), and the cost of the keyboard using mechanical switches has risen sharply.
