Anti-ghost membrane switch device

An anti-ghost membrane switch device, comprising:

• a first membrane layer comprising a first surface and a first output terminal, the first surface being provided with a plurality of first trigger points and a first signal line, the first signal line being electrically connected to the first trigger points and extending to the first output terminal;
• a second membrane layer disposed on the first membrane layer, the second membrane layer comprising a second surface and a second output terminal, the second surface facing towards the first surface and being provided with a plurality of second trigger points and a plurality of second signal lines, the second trigger points being respectively corresponding to the first trigger points, ends of the second signal lines being respectively electrically connected to the second trigger points, another ends of the second signal lines extending to the second output terminal, the second signal lines being not electrically connected with one another, the first signal line of the first membrane layer and the second signal lines being not electrically connected with one another;
• and
• a spacing layer between the first membrane layer and the second membrane layer, the spacing layer comprising a plurality of through holes, the through holes being respectively corresponding to the first trigger points and the second trigger points.
