| 摘要 | A keyboard system in which a plurality of spaced sets of conductive members including U and rivet shaped are arranged at a surface of a support in electrical communication with conductive paths on an opposite surface of the support. A plurality of actuatable conductive elements, one for each set of conductive members, are provided to establish bridging electrical connection between conductive members of a set upon application of a preselected deflecting force to the conductive elements. | ||||||
| 权利要求 | 1. In a selectively energizable keyboard system comprising an electrically insulating support member having a surface on which a plurality of conductive paths are disposed arranged in a preselected pattern adapted to transmit electrical information in response to selective interconnection of portions of said paths; a plurality of spaced apart generally U-shaped conductive members arranged in a preselected configuration on said support member in electrical communication with preselected portions of said paths, means for selectively establishing electrical connection for the conduction of electrIcal current between certain of said paths including a plurality of selectively actuable conductive elements, and means mounting said conductive elements adjacent but spaced from a surface of said support member, at least one of said conductive members being disposed adjacent each of said conductive elements, said conductive elements each being adapted for selective deflection into engagement with its said at least one conductive member in response to the application of a preselected deflecting force to said conductive element, thereby selectively to establish paths for the flow of electrical current between selected portions of said path. 2. A system in accordance with claim 1 wherein said conductive elements are each of a generally circular configuration having a convex surface of curvature adapted to receive the preselected deflecting force in registration with an associated U-shaped conductive member, said convex surface being adapted to be deflecting into a concave configuration in engagement with said U-shaped conductive member in response to the application of the preselected force. 3. A system in accordance with claim 1 wherein a relatively thin flexible insulating, force-transmitting overlayer is secured to said insulating support board in overlying relationship with respect to said conductive elements so as to maintain said conductive elements in position. |
