'''Cherry M11''' is a family of linear switches manufactured by [[Cherry]]. This switch has only been found on the [[HP 4953A]] protocol analyzer keyboard<ref name="HP4953A"/>. The heat sealing used to attach the shell to the base is very weak and is prone to tearing off when pulling a keycap. This is likely the reason the switch is so rare, because when the heat seal fails the switch falls apart. 

The M11-0101 schematic<ref name="M11-0101"/> indicates that the initial switch design was completed late 1979. Modifications were done in 1980 and was marked complete in 1981. The [[HP 4953A]] keyboard was introduced sometime 1984<ref name="hpcompmuseum"/>. The switch does not appear in the 1982 ''Keyboards and Switches'' catalogue.<ref name="Cherry_catalogue" />

The M11 switch used different slider colours to represent weightings. Black for (TODO weight) and white for (TODO weight).

The switch's identity is not proven. The M11-0101 schematic does not cite the family name, and based on other Cherry switch part numbers it stands to reason that "M11" means "M1, subtype 1". However, based on the dates found on the schematic, and the clear similarity to Cherry M8 and M9, which were not listed in the 1973 and 1974 catalogues, it could be considered reasonable to assume that "M11" does in fact mean "M-eleven". The confirmed switch types introduced after M9, are MX, MY, and ML, which sidestep the issue of dealing with two digit series numbers.
