Editing Cherry M7 (section)

==Nomenclature==
Being Cherry's first dedicated keyboard switch modules, the series originally had no name. Cherry described them as the 'Gold "Crosspoint" Contact Switch' or 'Key Module', but the descriptions varied. Part numbers began "M" (perhaps for "keymodule") and were divided up into subtypes based on characteristics, including M4, M5 and M6, and seemingly also M7. At some point in the late 70s, Cherry found cause to introduce additional keyswitch types, and the original switches were regrouped under M7 (perhaps as this was the highest subtype in use so far), gaining a series name of "Serie M7".

All Serie M7 switches have part numbers beginning M7, but for the purposes of classification, M4, M5 and M6 parts are being considered "M7" simply because the series had no concise name up until additional switches were introduced.
