ABSTRACT:
An enclosed matrix programming board or connecting means for joining two circuits includes connecting bars formed with split, cylindrical sockets for each connecting position and held in place by an insulator block formed with a hole for each connecting socket. Connecting pins are applied through a perforated cover plate and join a conductive bar placed in one position with a similar bar orthogonal to it. Each bar is connected to a pin extending a short distance from one of the cover plates for connection to an exterior circuit. Double connector pins, containing a diode in the handle, may be used to restrict the connecting current to one direction only. Parallel ribs are provided on the cover plates for mechanically and electrically isolating the connecting bars.
