Signature Plastics Parts Numbers
each keycap is designated by an intelligent part number (usually for internal use) - 6- digit part numbers are used mostly for keycaps that wind up in our inventory, but they too have an intelligent part number. The 14-digit portion of the part number indicates: family type, mount style, external description, internal description, keycap size, row and mount spacing. We then add our color code and a legend number. For example, the Q on your attached picture would have the following part number: 104U0000A12C00*NN/WA- Q838 - Meaning to production: 10(DCS ABS Family), 4U (Cherry MX Mount), 00 (no additional external information), 00 (no additional internal information), A1 (single space key), 2 (row 2), C (center mount), 00 (no mount spacing required), NN/WA - (Black 2nd shot/keycap body and White 1st Shot/legend), Q838 (legend number for the Q 0.187" tall located in the upper left corner of the keycap). We have over 500,000 legends in our legend library and sadly for me they are not cataloged on the computer, so I have no way of providing you this information 'preorder'. It would however, be exponentially helpful if from here on out I gave you our work orders containing these intelligent part number so re-orders or new orders with the same legends are the same - specifically from a legend standpoint.
