Actuation force in mechanical keyboard switches refers to the amount of pressure required to register a keystroke. It's the force needed to press down a key to a certain point where the switch actuates, signaling to the keyboard's circuitry that a key has been pressed.
Actuation force varies between different switch types and is a crucial factor in determining a keyboard's feel and typing experience.
Some switches have a light actuation force, requiring minimal pressure for keypresses, resulting in faster typing speeds and reduced fatigue during prolonged use. On the other hand, switches with heavier actuation force provide tactile feedback and require more deliberate keystrokes, favored by typists who prefer precision and accuracy. Understanding actuation force allows users to choose a mechanical keyboard that best suits their typing preferences and workflow.
