There are several types of keyboards, including:

Membrane keyboard: This is the most common type of keyboard found in most computers, and it uses a rubber dome under each key to register keystrokes. These keyboards are relatively cheap, quiet, and lightweight, but they don't provide the same tactile feedback as mechanical keyboards.

Scissor-switch keyboard: This type of keyboard is often used in laptops and has a scissor-like mechanism under each key, which provides a more stable and precise keystroke. Scissor-switch keyboards are usually quieter and thinner than mechanical keyboards.

Capacitive keyboard: This type of keyboard uses sensors to detect when a key is pressed. These keyboards are often found in touchscreens and can provide haptic feedback when typing.

Optical keyboard: This type of keyboard uses light to detect when a key is pressed. Optical keyboards are often faster and more durable than mechanical keyboards, but they are also more expensive.

Regarding the Apple keyboards, the older Apple keyboards (pre-2016) used scissor switches, while the newer ones use a butterfly mechanism, which is a type of low-profile mechanical switch. The butterfly mechanism has been criticized for being prone to failure and having a shallow typing experience.
