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:
MK Electric is a company that makes electrical accessories. The company's headquarters are in Basildon , Essex , England , from where it sells goods worldwide. History
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).
Keycap in a French Model M. The Model M keyboard was designed to be less expensive to produce than the Model F keyboard it replaced. Principal design work was done at IBM in 1983–1984, drawing on a wide range of user feedback, ergonomic studies, and examination of competing products.
Unicomp Model M with removed z key. The exposed buckling spring is visible. 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.
This was possible because of molding techniques that could provide very tight tolerances for the switch-plunger holes and guides across the width of the keyboard so that the key plunger-to-housing clearances were not too tight or too loose, either of which could cause the keys to bind. The use of contact-switch membrane sheets under the monoblock.
A keyswitch is a type of small switch used for keys on keyboards. Key switch is also used to describe a switch operated by a key, usually used in burglar alarm circuits. A car ignition is also a switch of this type.
