Abstract: Membrane switch assembly comprises a substrate, a membrane, and a separator between the opposed surfaces of the substrate and membrane. Opposed switch electrodes are provided on the opposed surfaces and circuit conductors are provided which extend between and among the electrodes. The assembly has a composite tail made up of a substrate tail section and a membrane tail section. The two tail sections are co-extensive and parallel. Substrate leads extend from the substrate onto the substrate tail section and membrane leads extend from the membrane onto the membrane tail section, the leads being parallel and offset from each other. Portions of the substrate tail section extend through slots in the membrane tail section and portions of the membrane tail section extend through slots in the substrate tail section.
