Abstract
In a membrane switch having at least one silver conductive lead terminating at a termination point for connection to an electrical connector, the improvement comprising a strip of non-migrating, conductive material applied over said conductive lead at least in a region adjacent to said termination point and extending a distance beyond the termination point of said conductive lead for receipt of said electrical connector affixed to and in electrical contact with said strip of non-migrating, conductive material at the extended portion thereof.
Claims6
In a membrane switch having at least one silver conductive lead terminating at a termination point for connection to an electrical connector, the improvement comprising a strip of a non-migrating, conductive material applied over said lead at least in a region adjacent to said termination point and extending a distance beyond the termination point of said lead for receipt of said electrical connector affixed to and in electrical contact with said strip at the extended portion thereof.
A method for preventing silver migration in the area in which the silver conductive leads of a membrane switch are attached to electrical connectors, said switch including at least one silver conductive lead terminating at a termination point, comprising:
- applying a strip of non-migrating, conductive material over said silver conductive lead at least in a region adjacent said termination point and extending a distance beyond said termination point;
- and
- affixing said electrical connector to said strip at the extended portion thereof.
