Let's take a look at the history of the Keypad. The first Keyboard was used on typewriters, and by the mid-20th century, the Membrane Keyboard had become the basic input device for computers. Mark Twain's on the Mississippi in 1883 was the first manuscript to be printed and therefore, indirectly, the first manuscript to be printed. Now the keyboard on the computer, can accept the type of letters, numbers, punctuation marks, and input signals into the computer can understand the instructions to operate.
There are two common types of keyboards: mechanical keys and membrane keys. The keyboards we use in our daily life are basically thin Membrane Keypads, while the mechanical keyboard has a micro Switch for each key to control the switch on and off, which makes the tapping feel good and very musical. For game players and programmers who love to work with games for a long time. The keyboard consists of a key cap and a circuit board underneath. The circuit board is the control core of the entire keyboard, located inside the keyboard, responsible for scanning the keyboard position, encoding and transmitting signals to the computer. When the keyboard is pressed, the plunger sinks, closing the two circuits that were previously disconnected, creating a path. The microprocessor then scans the location to determine which keyboard is pressed.
