ABSTRACT:
An insertion code arrangement for a bank of interchangeable circuit board modules in an electronic circuitry cabinet featuring a set of numbered pairs of code plates with permanently arranged code elements in the form of an integral code prong on each male code plate and a matching code slot on each female code plate, the male plates being snap-attachable to the contact edge of a circuit board module between upper and lower contact bars, and the female plates being clamped to the inside of the back panel of the circuitry cabinet. The laterally offset arrangement of the code elements on the code plates doubles the number of code patterns available from two identical sets of code plates, when one set of plates is rotated 180.degree..
