Editing Futaba linear switch (section)

==Description==
Futaba linear switches all use stout, cylindrical legs that are threaded at the top and screw in. The switch terminals are separate internal parts that the legs make contact with inside the switch.

Most types are plate mount, and have a square-top cylindrical shell with truncated sides. In these types, the shell contains the whole switch, and the internal parts are held in by a base plug. The base plug for larger switches is secured solely by the legs, while the small type also has a clip on the base to secure it in addition to the legs.

A final known type has a square or rectangular cross section to the shell and is sealed shut.

The number of parts between Futaba switches varies. MD series "complicated linear" momentary switches comprises sixteen parts. The sealed switches share the short legs with MD series so are likely to have the same internals. MR and ML series switches have simplified internals of only nine and seven parts respectively.

Futaba linear switches have a lower travel than many other switches; travel ranges from around 2.7 to 3 mm across the switch range.
