They have no click feel, and the pressure increases linearly from the beginning to the end. They meet the needs of both gaming and work. Recommended for those who dislike a pronounced click feel or for those using them in public spaces. ② Blue switches are called click switches, and they offer a pronounced mechanical feel. They become slightly heavier just before the switch fully engages, then lighter once they've disengaged. The internal mechanism of the switch produces a gentle click sound. They feature a classic typewriter-like feel. Recommended for those who prefer a click feel or for those using them in private spaces. ③ Brown switches are a perfect middle ground between blue and red switches. They offer a moderate click feel and key weight. They are the standard for mechanical keyboards and are popular with beginners. ⌨ [Details] ① Size: 149 x 134 x 39 mm ② Compatible systems: Windows (Windows XP or later) / Mac OS compatible
