MEMBRANE SWITCH AND CONNECTION SOCKET

摘要

A membrane switch has two membranes. Each membrane includes a substrate section and a tail section extending from the substrate section. Each membrane has a circuit surface and a back surface opposite to each other. The two substrate sections overlap with the two circuit surfaces facing to each other. One of the two tail sections has a bypass portion at least partially avoiding the projection of the other tail section in the normal direction of the other circuit surface. The distal ends of the two tail sections overlap with the two back surfaces facing to each other.

1. A membrane switch, comprising:
a first membrane having a first circuit surface and a first back surface opposite to the first circuit surface, the first membrane comprising:
a first substrate section; anda first tail section extending from the first substrate section, the first tail section comprising a first distal end; and a second membrane having a second circuit surface and a second back surface opposite to the second circuit surface, the second membrane comprising:
a second substrate section; anda second tail section extending from the second substrate section, the second tail section having a bypass portion and a second distal end;wherein the first substrate section and the second substrate section overlap with the first circuit surface facing the second circuit surface;wherein the bypass portion and the first tail section are non-overlapped so that the bypass portion is able to pass through a plane where the first tail section is located;wherein the first distal end and the second distal end overlap with the first back surface facing the second back surface.
