Kailh BOX switches are IP56 rated to keep dust and moisture out. Created with a box around the cross stem instead of the cross stem just sticking up, they’re built to avoid corrosion and debris buildup. The box extends to the contact plate and leaf, providing extra protection. Kailh BOX Jade Switches features a thicker clickbar which produces a more pronounced and deeper "click" as well as drastically improve the overall tactile feedback.
