Editing Futaba MR-6C series (section)

==Description==
Like most other Futaba linear switches, the shell is cylindrical with truncated sides, with a square top above the plate. It sits in a circular hole in the plate. The legs are threaded at the top and screw into place; the base plug of the shell is retained in place by the legs. One leg screws into a hole in the lower contact leaf; the slider presses both contact legs up against the other leg.

This switch is found in very few types of equipment; in most instances of it being identified, the actual switch used is [[Futaba MD series]] "complicated linear", which is visually distinct from MR-6C in terms of shape (colour should not be considered). Despite the cheapness of the simplified switch, it proved itself as a robust and durable product, standing up the wear and tear of the United Kingdom's schoolchildren in the 1980s. It was superseded in Acorn's range by the [[Futaba low-profile linear]] switch (in the Electron and Master 128), which was nowhere near as durable.

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 [[printed circuit board|PCB]] is 12.7 mm. Travel is around 3 mm.
