Great for those who are a bit messier at the keys, Kailh BOX switches are IP56 rated to keep dust and moisture out.

The box extends to the contact plate and leaf, providing extra protection. This version of the switches features a thicker clickbar for a deeper sound than before. The feel is slightly more substantial. Utilizing the already popular Cherry MX form, Kailh BOX switches provide an easy transition so you don't have to let go of your existing keycap collection.
