ABSTRACT:
An apparatus for providing hitless by-pass switching for signal flow paths on a circuit board. The switches for establishing the by-pass path(s) are mounted adjacent to the connector into which the board is inserted. The circuit board has mounted thereon an apparatus which engages the by-pass switches in a manner so as to open the switches and maintain them open when the board is essentially fully inserted in the connector. Otherwise, the switches are closed. The signal flow paths on the board are conductive when the board is both fully and partially inserted in the connector. When the board is partially inserted in the connector, both the by-pass and circuit board paths are conductive.
