Abstract
A contact switching arrangement with a flat electrically non-conducting cover which forms a switching area on a top facing the user, and has an underside facing away from the user, at which at least one electrode is arranged and is connected with a switching arrangement for triggering a contact signal when a finger of the user or a similar conducting body approaches. The cover has a light-reflecting, electrically non-conducting film, at least over portions, which acts as a non-conductor. The contact switching arrangement is for use in connection with control panels of electronic devices, for example.
