Further, one end of above-mentioned conductive pole is fixed on upper film layer, and its other end is fixedly connected with lower thin layer through intermediate thin rete, and insulate and contact between this conductive pole and intermediate thin rete.
Further, on above-mentioned the first transparent watertight film and the second transparent watertight film, be equipped with and be convenient to press the frosted region putting in place.
Further, the surface of above-mentioned combined type touch film switch is the diagram shape being centrosymmetric.
Further, the surface of above-mentioned combined type touch film switch is circle or regular polygon.
Combined type touch film switch of the present utility model is except possessing conventional films switch advantage, also: a plurality of thin film switches are combined into composite structure, and modern design, handle effect is good, can realize several functions in the centralized management in auxiliary bond district; By pressing of major key realized to scene in real time, promptly, security control easily, be convenient to promote the use of.
