As time goes on, there are more and more switches being developed and manufactured across the world. Some are by new manufacturers, some are collaborations between companies and manufacturers, and some are consumer made.
Mechanical keyboards (or mechanical-switch keyboards) are computer keyboards which have an individual switch for each key. The following table is a compilation list of mechanical keyboard models, brands, and series:
Among Cherry's widely known products are its line of MX and ML key switches, including red, blue, and brown switches, that have been used in industrial electronics and point of sale environments since their inception in the 1980s, and more recently (~2008) by numerous manufacturers of consumer PC keyboards.
The most common of these are the piano, organ, and various electronic keyboards, including synthesizers and digital pianos. Other keyboard instruments include celestas, which are struck idiophones operated by a keyboard, and carillons, which are usually housed in bell towers or belfries of churches or municipal buildings.

Hot-swappable keyboards are keyboards in which switches can be pulled out and replaced without requiring the typical solder connection. [7] [8] Instead of the switch pins being directly soldered to the keyboard's PCB, hot-swap sockets are instead soldered on. Hot-swap sockets can allow users to change different switches out of the keyboard ...
The earliest known keyboard instrument was the Ancient Greek hydraulis, a type of pipe organ invented in the third century BC. [2] The keys were likely balanced and could be played with a light touch, as is clear from the reference in a Latin poem by Claudian (late 4th century), who says magna levi detrudens murmura tactu . . . intonet, that is "let him thunder forth as he presses out mighty ...
Mellophone fingerings are the same as the trumpet. [3] It is typically pitched lower, in the key of F or E ♭. The overtone series of the F mellophone is an octave above that of the F horn. The tubing length of a mellophone is the same as that of the F-alto (high) single horn or the F-alto (high) branch of a triple horn or double-descant horn.
Alternatives to the Mellotron were manufactured by competitors in the early to late 1970s. The Mattel Optigan was a toy keyboard designed to be used in the home, which played back sounds using optical discs. [73] This was followed by the Vako Orchestron in 1975, which used a more professional-sounding version of the same technology.
