Editing RAFI full-travel key switch (section)

===Codes===
RS 76 switches are often found with codes stamped into the top of the switch. For a code such as "1245 502H", found in switch family RS 76 M, this gives part number 3.13.002.502. The meaning of "H" and the preceding digits is not known. Comparison of two "1245 502H" switches shows that a stamp tool was used, as the tracking and orientation of the characters is entirely consistent between switches; the writing appears to be recessed, suggesting that the switch was stamped, as mould stamps lead to raised text in the moulded article. The <ref>Deskthority — [https://deskthority.net/keyboards-f2/rafi-dt-02-t10906.html RAFI DT-02]</ref> keyboard is a counterexample of RS 76 M where the stamped numbers don't appear to include the switch part number, only the preceding digits, which may indicate the batch number.

Many moulds themselves feature part number codes on the bottom (e.g. ".516" for "1245 502H"), but these do not appear to correspond to switch part numbers and may instead indicate the mould pattern, as moulds were shared between switch variants; this may explain why the specific switch part numbers were often stamped in afterwards.
