  • Patent number: 4855611
    Abstract: The invention relates to a change-over switch suitable for use in the case of connecting, e.g., a camera integrated type VTR to a television receiver. A first input terminal and an output terminal are closely arranged. The first input terminal, the output terminal, and switching means are connected by a parallel line consisting of first and second signal lines. The first input terminal and the output terminal are connected by the first switching operation. The second input terminal and the output terminal are connected by the second switching operation.
