Abstract

Each character on a keyboard is assigned a unique scancode independent of its position on the keyboard. The keyboard is constructed so that the user or field engineer may rearrange the keys by removing a key or key top from one key position and placing it at another. The key produces the same scancode regardless of its position. This allows rearrangement of keys without any software support. The keyboard contains an array of pads with one pad corresponding to each key position. Each key position in the keyboard has a pad identical to the pad at any other position. Each pad comprises a multiplicity of contact points or switches.
