What is the difference between a mechanical keyboard and an ordinary keyboard

According to the working principle of the keyboard and the different ways of pressing keys, it can be divided into four kinds:

A. Mechanical Keyboard Adopting similar metal contact switches, the working principle is to make the contacts conductive or disconnective, which is characterized by simple process, high noise and easy maintenance.

B. Plastic Membrane Keyboard The keyboard is **** divided into four layers internally, realizing no mechanical wear and tear. It is characterized by low price, low noise and low cost, and has a considerable share of the market.

C. Conductive Rubber Type Keyboard The contacts are structured to be connected by conductive rubber. There is a layer of raised electrically charged conductive rubber inside the keyboard, and each key corresponds to a bump that turns the contact underneath on when pressed. This type is commonly used by keyboard manufacturers.

D. Capacitive Keyboards Use a principle similar to that of capacitive switches to actuate an encoder by changing the capacitance caused by changing the distance between the electrodes when a key is pressed. It is characterized by no wear and tear and better sealing.
