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:
IBM's Model F keyboard is a design consisting of a buckling spring over a capacitive PCB, similar to the later Model M keyboard, but instead used membrane sensing in place of a PCB. The Topre Corporation design for switches uses a conical spring below a rubber dome. The dome provides resistance, while the spring does the capacitive action. [10]

Among the first proper wireless mechanical keyboards, and the first one from a major, popular manufacturer. Romer-G switches are without RGB lighting to improve battery life Can connect up to two devices via 2.4 GHz wireless and Bluetooth, also compatible with iOS and Android devices as a keyboard input.
Wireless keyboards in the current market are commonly accompanied by a wireless mouse. Wireless keyboards based on infrared technology use light waves to transmit signals to other infrared-enabled devices. In case of radio frequency technology, a wireless keyboard communicates using signals which range from 27 MHz to up to 2.4 GHz.
The earliest name was Keyboard Video Switch (KVS). [2] With the advent of the mouse, the Keyboard, Video and Mouse (KVM) switch became popular. The name was introduced by Remigius Shatas, the founder of Cybex (now Vertiv), a peripheral switch manufacturer, in 1995. [3] Some companies call their switches Keyboard, Video, Mouse and Peripheral (KVMP).
A wireless keyboard may use industry standard Bluetooth radio communication, in which case the receiver may be built into the computer. Wireless keyboards need batteries for power, and may be at risk of data eavesdropping. Wireless solar keyboards charge their batteries from small solar panels using natural or artificial light.
Another example is the Emacs editor, which makes extensive use of modifier keys, and uses the Control key more than the meta key (IBM PC instead has the Alt key) – these date to the Knight keyboard, which had the Control key on the inside of the Meta key, opposite to the Model M, where it is on the outside of the Alt key; and to the space ...
