Abstract
This invention relates to flexible materials for use in electrical devices, such as membrane switches. The flexible component of the device is formed of paper.
Claims7
An electrical switch having a flexible component made of paper said flexible component having electrical conductive areas printed thereon.
A membrane switch of the type having a flexible membrane, a substrate, facing patterns of conductors printed on the membrane and substrate respectively, and an insulative spacer disposed between the conductor patterns to normally hold them in non-contacting relation, the spacer having openings therein such that aligned portions of the conductor patterns may contact each other in response to pressure on the membrane whereby the membrane is moved through a spacer opening to contact the substrate, the improvement comprising a membrane made of flexible paper.
