Editing Futaba linear switch (section)

==Variants==
===Futaba MD series===
{{Main|Futaba MD series}}

MD series "complicated linear" is the most common series, found in a number of forms including momentary and alternate action, upright and angled keystem, short and tall keystem, and illuminated. The single confirmed part number is MD-4PCS.<ref name="MD-4PCS" /> Different switch colour combinations exist, and these colours have not yet been decoded.

The switch 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. The distance between the plate and PCB is 12.7 mm.

The switch comprises 16 parts in total.

===Futaba MR series===

The simplified variant of the switch is physically compatible with the complicated variant, but uses only 9 parts: the complex contact assembly is replaced with bare contacts. The contacts remain distinct from the terminals, as with the complicated designs.

MR-6C series has been shown to contain the only type ever encountered; no documented evidence for MR types beyond MR-6C has yet been discovered. MR-6C itself is known only from a few types of equipment.

The switch actuates at mid travel, at around 60 cN.

===Futaba ML series===
{{Main|Futaba ML series}}

ML series represents a reduced-size version of MR series. Differences include the plate retention clips being attached to the base plug instead of the main shell, and the pins being offset towards the front of the switch.

[[Keycap mount]] compatibility is maintained with the larger switches.

===Sealed type===

The small square type appears to have similar internals to MD series, but the shell is square and the switch is sealed.
