Abstract: The invention is a method and apparatus for utilizing finger control switches connected to a binary code receiver for the purpose of driving a printer and/or a visual and/or audible readout device. The device is made up of a number of switches normally in the open position which can be depressed to a closed position. The input from the switches is communicated to a binary code receiver, which activates a printer, a visual readout or an audible device. The apparatus is used both for communication to other equipment and as a teaching device for physically demonstrating the combination of switch positions required to produce a given command.
