Editing Futaba MD series (section)

==Variants==
===Cross mount===
The cross mount version has a non-uniform cruciform [[slider]] approximately 4.0 mm by 4.7 mm, with 1.2 mm wide arms, taking a 4 mm deep [[keycap]] stem. It has been seen in black with an orange base cap, white with an orange base cap, all black<ref name="EBAY-Altair" />, and all white.

The white/black/orange version has part number MD-4PCS. GRI KBM switches are also this variant.

The cross mount variant is keycap-compatible with the [[Futaba simplified linear]] switch.

The [[Futaba linear lock]] switch is the [[alternate action]] switch in this family.

===Bar mount===
All-black shell with a white slider<ref name="Sandy-bar_mount" />, white<ref name="eBay-PTC-45A" /> (base plug not visible), and black with an orange base and white slider.<ref name="GH-BP1210-D" /> One minor difference between the examples examined, is that the bar mount variant was found to have a transparent plastic cover over the contact assembly, instead of black rubber-like material.

This version may be model MD-4P.<ref name="ecplaza" />

===Multiple-switch return key===
TeleVideo keyboards (specifically TS-800A, TS-802 and TS-825) have been found with dual switches for the Return key. <ref name="GH-TeleVideo-8xx" /> These switches are white with a cream base plug, and otherwise appear to be identical to the white/orange switches used on the rest of the keyboard. The reason for having two switches side by side instead of a stabiliser is not known, nor why the switches are a different colour.

===Illuminated===
The illuminated version, with a crucform keystem, is given as MD-7;<ref name="ecplaza" /> it is not clear whether this is a series name or model number.
