A:Answer This is the yellow switch version. Razer currently has 3 switches...green, orange, and yellow. The green are their normal mechanical switches. They have a longer press and a distinct click sound when pressed. The orange is their stealth model. It is still mechanical but has a much quieter sound. The yellow has a 1.2 mm travel time for activation...much quicker than the greens and oranges. They also have the stealth feature so they are quieter than the greens.
