Since the 80s of the 19th century, a mechanical keyboard called "typewriter" has gradually appeared in the office, and its biggest feature is the sound of mechanical impact every time the key is pressed. Does this sound familiar? That's right, the popular mechanical keyboards now feel the same way.
Different people have different needs for typing and typing, so this mechanical keyboard was able to become popular again after being replaced by a "modern keyboard" film. The variety of keyboards of various types makes us even more dazzled when purchasing.
What is the difference between thin film, mechanical, electrostatic capacitance and optical axis
Types of keyboards are classified according to the switch structure and trigger principle. At present, the mainstream types are membrane keyboards, mechanical keyboards, capacitive keyboards and optical axis keyboards.
Key trigger mechanism for mechanical keyboards
The mechanical keyboard is soldered to each individual mechanical axis on a huge PCB plate. Each mechanical axis corresponds to a button. Every time the button is pressed, the shaft core in the mechanical shaft that is supported by the cylindrical spring will be pressed down, and the downward pressure will press against one metal piece in the shaft to make it contact with another metal piece, and the button will be triggered at this moment.
Cherry axes (including other Cherry-like axes), Omron axes, and ALPS axes are triggered by the touch of a metal piece by a button. The composition of each switch is the same (core, spring, metal sheet), but the shape and placement/orientation of each part are different, resulting in different feel, sound, and manufacturing costs.
I dismantled a switch by myself, taking the blue axis as an example, as shown in the figure below:
