Editing Futaba MD series (section)

==Nomenclature==
The series name MD-4P is cited by Korean website ePartsHub, with a picture of Sandy's bar mount switch and the description "various switches".<ref name="epartshub" /> With MD-4PCS being a known part number, this would put both bar and cruciform mount in the same series. However, the cruciform mount, illuminated version is cited by a related website as "MD-7", suggesting MD-4P is the bar mount version, MD-4PCS is the cruciform mount version, and that "MD" is the common aspect of the part numbers.<ref name="ecplaza" /> Provisionally this is being used as the series name.

ePartsHub cite the switch as being made by Sejin. The only known PCB photograph of the Futaba [[Texas Instruments TI-99/4A]] keyboard bears both the Futaba and Sejin logos, but all cited instances of the product family (Futaba MD-4PCS, the [[Acorn BBC Microcomputer]] simplified linear switches, and the complicated linear switches in the [[Lear Siegler ADM 36]]) all cite simply Futaba as the source. While Sejin may have been the manufacturer, the series was clearly marketed by Futaba.

The previous "complicated" moniker arose due to the significantly greater complexity over the visually very similar [[Futaba simplified linear]].
