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 Spring has featured a light guide column on the build that passes through the RGB effects of the keyboard kit. The switches have an extended 20mm long spring that gives them an enhanced rebound experience during typing. Kailh BOX Spring switches have super smooth typing with tactile feedback that gives a satisfying experience for the users.
