Comments on Kailh Deep Sea Silent Pro Box Islet switches
The Kailh Deep Sea Silent Pro Box switch is the descendant of the original Kailh Deep Sea Silent Box switch. This new switch features a blue transparent PC cover, a dark blue nylon base, and a transparent prolong stem to give the feeling of the deep sea. It looks like art on a keyboard and provides a more stable and quiet feel. The extended spring has a more uniform pressure force and faster rebound than the ordinary spring. The pro switches have better backlight transmittance than the original switches because of their transparent cover and tapered light guide to allow more light to shine through to the typist or gamer – kailh.net.
