Switchable Spare Line in Multi-Line Cable

      Disclosed is a switch mechanism that permits switching of
signal lines in a cable to a spare line.  A rotating switch is
disclosed that can be incorporated into the cable connectors or at
the terminius of a series connected set of cables.

      Many cables have multiple signal lines and if one fails, the
cable must be replaced.  Disclosed is a mechanism that permits
switching of a failed signal line to a spare line.  Multi-line signal
cables are used in many areas of computers and communication
networks.  Many have spare signal lines that may be used should a
primary line fail.  This avoids the necessity to replace the entire
cable.  This is illustrated in Fig. 1.  Disclosed is a mechanism that
permits switching in a cable designed with spare lines.  Fig. 2
illustrates a mechanism that permits a signal to either pass thru or
be routed to a spare line.  The clear circle symbol represents a pass
thru while a solid circle switches to the spare line.  The pass thru
can be implemented as a spring loaded contact that permits the
contact to slide.  The switch to spare is a similar contact except
the source is a spare line.  The movable part is sandwiched between
two fixed parts that hold the wires that are the signal lines.

      Fig. 3 illustrates a linear switch where the six positions have
three with pass through contacts, one with a contact to the spare
line, and two that are pass thru contacts.  The in...
