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:
Cherry's color-coding system of categorizing switches has been imitated by other switch manufacturers, such as Gateron and Kailh among many others. [4] [5] Keyboards which utilize this technology are commonly referred to as "mechanical keyboards", but there is not a universally agreed-upon clear-cut definition for this term. [6]
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.
The key switches are connected via the printed circuit board in an electrical X-Y matrix where a voltage is provided sequentially to the Y lines and, when a key is depressed, detected sequentially by scanning the X lines. The first computer keyboards were for mainframe computer data terminals and used discrete electronic parts.
Key rollover is the ability of a computer keyboard to correctly handle several simultaneous keystrokes. A keyboard with n-key rollover (NKRO) can correctly detect input from each key on the keyboard at the same time, regardless of how many other keys are also being pressed.

[2] [3] Key switches are available as components with solder connections, and are available with a variety of ampere ratings. They may use tubular or other ...
Silicone Key web design. The technology uses the compression molding properties of silicone rubber to create angled webbing around a switch center. On depression of the switch, the webbing uniformly deforms to produce a tactile response. When pressure is removed from the switch, the webbing returns to its neutral position with positive feedback.
Without using moving parts, they are called solid state switches, which distinguishes them from mechanical switches. [ 1 ] Electronic switches are considered binary devices because they dramatically change the conductivity of a path in electrical circuit between two extremes when switching between their two states of on and off .
