Kailh Box switches

Identifying a Kailh box switch is pretty easy: just look for the box enclosure that surrounds the familiar cross-shaped MX style stem. This box protects the switch from dust and moisture, and provides an IP56 resistance rating. However, the mechanism means that they’re only compatible with SMD LEDs, rather than the (slightly more common) through-hole LEDs.

There are four different varieties thus far, each with a different colour: Box Red, Box Brown, Box White and Box Black. Again, if you’re familiar with the default switches, you can guess some of their characteristics: Box Red is a light linear switch, Box Black is a heavier linear switch, Box Brown is tactile and Box White is clicky.

Interestingly, each Box switch has the same travel and actuation distances: 1.8mm for actuation and 3.6mm in total. That’s a little shorter than the Default switches, and you can feel a bit of a difference when it comes to speed.

Here’s a YouTube video by Kailh that shows off the new switches:


once again, here’s the summary:

  • Kailh Box Red: soft linear

  • Kailh Box Black: heavy linear

  • Kailh Box Brown: tactile

  • Kailh Box White: clicky
