Mechanical Keyswitch
The mechanical keyswitch keyboard is the ancestor of keyboards.
It was the first type of keyboard ever introduced, and it is gradually
being removed from today’s technology drive. A keyswitch keyboard works
on the basic principle of completing a circuit. When you press a key, a
plunger moves down and forms an electric connection between two wires/plates.
The keyboard controller recognizes the closed circuit and transfers the
data to the computer that a specific key has been pressed. Then, after
the user releases his or her finger, the circuit is open, and the plunger
returns to its’ original position. On a typical keyswitch keyboard, there
will be approximately 100 individual keyswitches.
