Button switch production method for a switch's structure, includes an electric switch element made up from multiple plastic foils overlaid as a stack and interlinked by materials

摘要

A material that has a higher distortion temperature than a foil material produces each electric button switch element (EBSE) (2) in a foil (5) stack so that inside the switch element there is a cavity (9) separated by this material against a surrounding foil material. The EBSE fits in a card body (4) together with a chip module (3). A chip card (1) consists of seven plastic foils. An independent claim is also included for a structure with an electric switch element.
