Abstract
An article of manufacture having an in-molded capacitive switch and method of making the same are shown and described. In one disclosed method, a conductive ink sensing zone is printed on a film. The film is formed to a desired shape and put in an injection mold. A molten plastic material is introduced into the injection mold to form a rigid structure that retains the film.
