摘要： An improved capacitive keyboard uses a standard printed circuit board provided in various locations with spaced conductor pairs. A conductive disc with a flat insulated lower surface is aligned above each conductor pair. All of the discs are suspended above the printed circuit board within apertures of a web of polymer foam material and held in position by a sheet of adhesive covered plastic that covers and adheres to the entire upper surface of the web and each of the discs.
