ABSTRACT OF THE INVENTION A piggyback code switch which provides a unique digital code for various types of circuits, for example, garage door openers, load management control receivers, etc., is used with dual-in-line packaging diodes or resistor arrays in such a manner as to enable any combination of resistors or diodes to be pulled to a preselected voltage level and thus provide such circuits with a common starting code. A switch comprising an array of pins extending from a conductive base is placed atop a DIP network. Specific DIP resistors are shorted together by selectively removing the pins of the switch in accordance with a prearranged coding plan. This provides each circuit with a unique digital identification code.
