Commonly used mechanical switches on pre-built keyboards. Manufacturers frequently build computer keyboards using switches from original equipment manufacturers ...
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 ...
A keyboard matrix circuit is a design used in most electronic musical keyboards and computer keyboards in which the key switches are connected by a grid of wires, similar to a diode matrix. For example, 16 wires arranged in 8 rows and 8 columns can connect 64 keys—sufficient for a full five octaves of range (61 notes).
Splitting the keyboard at a given point allows a musician to play, for example, a bass guitar sound with the left hand and a piano sound with the right hand. Layering timbres allows a musician to play, for example, a pipe organ sound and a string ensemble sound together. Combinations of keyboard splits and layers may be possible.
Electric keyboards began with applying electric sound technology. The first was the Denis d'or stringed instrument, [5] made by Václav Prokop Diviš in 1748, [6] with 700 electrified strings. In 1760, Jean Baptiste Thillaie de Laborde introduced the clavecin électrique, an electrically activated keyboard without sound creation.
A buckling spring is a type of keyswitch mechanism, popularized by IBM's keyboards for the PC, PC/AT, 5250/3270 terminals, PS/2, and other systems. It was used by IBM's Model F keyboards (for instance the AT keyboard), and the more common Model M. It is described in U.S. patent 4,118,611 (Model F) and U.S. patent 4,528,431 (Model M), both now ...

[17] [14] A foot switch allows the player to switch between clavinet, pianet, or a mixture or the two. There is also a "split keyboard" mode that allows either instrument to be used in a particular range of notes. There is a stereo output jack, that allows either a mix of the two sounds or each individual sound on one half of the stereo channel.
