Membrane Switches typically consist of a polyester graphic overlay and spacers on a flexible silver printed circuit. The simplicity of Membrane Switch construction makes it easy to design and one of the lowest cost switch options available. The Graphic Overlay provides a natural fluid barrier and its long life cycle capabilities make it the right product for many applications.
