Abstract
Membrane switch technology is applied to the more conventional switch construction found in a rotary switch and a slide switch. Specifically, there may be a membrane and a substrate, each having electrical contacts or contact means formed thereon. A spacer having openings or opening means is positioned between the membrane and the substrate. In the slide switch embodiment, a slide or movable member moves in the spacer opening with the slide forming either the connection between spaced contacts on the substrate or spaced contacts on the membrane and substrate.
