Capacitive Keyboard

What Does Capacitive Keyboard Mean?

A capacitive keyboard is a type of computer keyboard that uses a change of capacitance on a keyboard's capacitor pad to detect a pressed key. This type of keyboard provides functionality similar to a standard mechanical keyboard, but its internal structure makes depressing a key quicker and quieter.


Techopedia Explains Capacitive Keyboard

Capacitive keyboards work primarily by detecting the change in capacitance on a capacitor pad, spread across the whole keyboard.

How capacitive keyboards work

Unlike traditional keyboards, where electricity flow initiates internally when a key is pressed, electricity is always flowing in capacitive keyboard.

Under each key, static charges are stored in capacitors. When a key is pressed, it connects with the capacitor pads and changes the capacitance at that specific point on the capacitor pad, which the keyboard identifies and registers as the exact keystroke/key.

Capacitive keyboards are faster than contact keyboards as they only require a gentle push to register a keystroke.
