An introduction to Kailh switches, including Speed & Box

The most popular article we’ve ever published is a guide to Cherry’s MX switches, which lie at the heart of many mechanical keyboards. However, Cherry are far from the only company producing switches these days, and one increasingly popular alternative are Kailh switches made by Chinese firm Kaihua Electronics. Here’s everything you need to know.

What Kailh switches are there?

There are three main families of Kailh switches:

  1. Default: switches made to mimic Cherry’s original designs
  2. Speed: switches with shortened travel and actuation distances
  3. Box: switches with the stem surrounded by a box for protection

Like Cherry MX switches, different Kailh switches have different colours and corresponding characteristics. We’ll cover each of them in turn, explaining how their construction differs and what they’re like to use. After that, we’ll look at some other common questions and answers regarding Kailh switches.

1. Default Kailh switches (Blue, Brown, Red)

Kailh produce switches that operate near identically to Cherry’s original designs; these are legal clones. If you’re familiar with Cherry’s switches, these Kailh alternatives require little introduction: Blue is a tactile and clicky switch, Brown is a tactile switch, and Red is a light linear switch. We’ll call these Default switches, in absence of any existing nomenclature.

According to testing by Input Club, there are some differences between the average Kailh switch and the average Cherry switch: the Red switches require a little extra force to actuate, the Blue switches require a little less, while the Brown switch is subtly different as it feels a little more… tactile. Despite these changes, the overall typing experience is quite similar.

2. Kailh Speed switches (Silver, Copper, Bronze, Gold)

As explained earlier, speed switches are essentially shortened versions of existing MX-style switches, allowing for faster actuation and intended for gaming. While Cherry produce a shortened linear switch, the Speed Silver, Kailh have produced four different shortened switches: Silver, Copper, Bronze and Gold.

The Kailh Silver switch is much like Cherry’s Speed Silver: an extremely light (27cN) linear switch with shortened travel (3.5mm) and actuation (1.3mm) distances.

The Kailh Copper switch is a soft tactile switch, with a tactile bump and actuation point just 1.1mm into its 3.6mm travel distance. Combined with its light (30cN) actuation force, and you’ve got a switch that can handle both gaming and extremely rapid typing — definitely one to try.

Kailh’s Bronze and Gold are clicky speed switches. That’s interesting because Cherry’s clicky switch, the Blue, is also one of its heaviest, requiring the most force to actuate. In comparison, the Bronze and the Gold switches provide that same audible clicky feedback, but they have the short actuation distances and minimal actuation force of other speed switches — cool!

The Kailh Gold is more traditional in its construction, akin to a Blue switch but requiring less force and actuating faster to make it more suitable for gaming.

The Bronze switch is more novel, with a second spring that provides the actual click sound effect. The resulting switch is somewhere between the Gold and the Blue when it comes to the force required (30cN, 40cN & 50cN) and tactile bump distance (1mm, 1.4mm & 1.5mm).

So, to sum up, here are the four speed switches:

  • Kailh Silver: soft linear
  • Kailh Copper: soft tactile
  • Kailh Bronze: soft clicky
  • Kailh Gold: very soft clicky

3. 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

Frequently Asked Questions

How do you pronounce Kailh?

Kailh is usually pronounced the same as kale, that leafy cabbage. However, it’s a Chinese word and other pronunciations are relatively common.

Are Kailh switches as reliable as Cherry ones?

Based on on our own testing and general sentiment in the mechanical keyboard community, Kailh switches are every bit as reliable as those made by Cherry. The company has been making switches for decades, and its new models show the company’s interest and skill in this area.

Are there other Kailh switches?

Yes, for sure. There are tons. For example, the switches above are clicky low-profile switches — an interesting combination that brings to mind the best laptop keyboards!

However, these three main groups are the most commonly available and/or interesting to talk about. If you’d like us to cover a different Kailh switch, let us know!
