Membrane touch panel having improved conductor construction
First Claim
1. In a transparent flexible membrane touch panel having contacts comprised of a first set of thin conductive metal film strips formed on a first layer, and of a second set of thin conductive metal film strips orthogonal to said first set and formed on a second layer, said second layer being spaced apart from and selectively movable into contact with said first layer, the improvement comprising silver conductive leads formed on each of said layers, each lead being integrally affixed at one end to, in electrical contact with, and extending from a respective one of said strips for connection to external circuitry.

Abstract
A flexible membrane touch panel switch having contacts comprised of a first set of thin conductive metal film strips formed on a first layer, and of a second set of thin conductive metal film strips orthogonal to the first set and formed on a second layer, the second layer being spaced apart from and selectively movable into contact with the first layer, the panel further having silver conductive leads formed on each of the layers, each lead being integrally affixed at one end to, in electrical contact with, and extending from one of the strips for connection to external circuitry.
