Good to know - These Razer switches are smooth and silent, thanks to the built-in sound dampeners - With zero distance between actuation and reset points, this switch is built for speed - Each key has an LED lens to brighten your keyboard's backlight and add some flare - With a 100-million keystroke lifespan, you won't be replacing these any time soon - They are perfect for Razer keyboards, but they'll work with most hot-swappable keyboards
