Abstract
Abstract An electric contact for connecting a conductive system present on an insulating substrate, in particular for automobile windshields, in which the conductive system is connected via a conductive path with an electric mating contact. A moisture-resistant electric contact which is easy to manufacture and can be universally used consists of a conductive path which is disposed directly on a support substrate as a path-shaped conductive layer on which an electric connecting line of the conductive system is located.
