ABSTRACT:
A keyboard system has an insulating support having a first surface on which conductive paths are arranged. A plurality of spaced sets of U-shaped conductive members are arranged at an opposite surface of the support in electrical communication with first portions of the conductive paths and U-shaped contact members are associated with the sets of conductive members on said opposite surface of the support in electrical communication with second portions of the conductive paths. A plurality of selectively actuable conductive elements are provided in continuous electrical contact with respective sets of conductive members in disengagement with the associated contact members to be selectively deflected into engagement with selected contact members to establish bridging electrical connection between the selected conductive members and contact members for electrically connecting first and second preselected portions of the conductive paths.
