Gateron’s Mechanical Switches for 2020: Waterproof, Magnetic, and Low-Profile

Kannon Yamada 22-01-2020

Gateron, a manufacturer of high-quality mechanical switches for keyboards, announced their newest and greatest products for 2020: a range of colored switches which include magnetic, low-profile, waterproof, tactile, linear, and clicky options. Most are simply upgrades of their 2019 models but a handful are entirely new technologies.


Gateron provided me with a grab-bag of their old and new switch options. This very brief summary will cover Gateron’s new switch options and how they compare to already announced products from their competitors at Cherry.

The 2020 Gateron Lineup

The current Gateron lineup includes magnetic, waterproof, and low-profile switches, which require special Printed Circuit Boards (PCBs) in order to work. In other words, Gateron’s magnetic, waterproof, and low-profile switch technologies are not compatible with the Cherry-MX standard which dominates today’s keyboard market. However, the magnetic and waterproof switches will work with Cherry-MX key-cap stems.

Gateron Low-Profile KS-21 Switches

First up is Gateron’s low-profile switches. These come in Blue, Brown, and Red colors. As with most of Gateron’s switches, the stem colors are carbon copies of Cherry switches. As with Cherry’s color-nomenclature, they are as follows:

  • Low-Profile Brown: tactile, 2.5mm travel, 1.5mm actuation, 50g force
  • Low-Profile Blue: clicky, 2.5mm travel, 1.5mm actuation, 52g force
  • Low-Profile Red: linear, 2.5mm travel, 1.5mm actuation, 45g force

The new switches will compete against Kailh’s “chocolate” switches and Cherry’s low-profile models. I don’t see much of a difference between Kailh and Gateron’s KS-21 and chocolate models. In dimensions, the Gateron low-profiles come in at 8.3mm height from the top of the stem to the bottom of the switch housing. The plastic PCB anchor is another 2.6mm in height (total height of 10.9mm). Gateron’s offering comes in at 0.10mm longer, equivalent to the Kailh Chocolate switches. Cherry advertises a height of 11.9mm.


While Gateron’s Cherry-clones, depending on the model, feel smoother and less scratchy than products from Cherry and Kailh, its low profile options seem virtually identical to the Kailh Chocolate switches. But that’s not bad. Low-profile keys are rattle-free and their boxier stems allow for less dust to penetrate into its inner workings. On top of that, going off the dimensions, it appears that the KS-21 can use key caps designed for the Kailh Chocolate switches. Although, at present, there are precious few key caps available in the Chocolate form factor.

And then there are some unfortunate design decisions. First, going off the measurements, it appears that Gateron KS-21 switches aren’t compatible with the same boards as Cherry’s low-profile. Nor are they compatible with Cherry key caps. On top of that, the KS-21 uses a slightly different pin configuration than Kailh boards—which means they require special PCBs.

Gateron Magnetic KS-20 Switches

Gateron’s magnetic switches (model number KS-20) will bring with them the deep 4mm of travel expected of desktop class mechanical switches along with extreme lightweight actuation force of 30 grams of weight. The magnetic switches also have less variation in their actuation force (+/- 10 grams instead of 15 grams).

Their key selling point is their massively enhanced durability versus standard mechanical switches: they last for double the amount of time of regular Cherry switches. Instead of 50 million presses, the KS-20 is rated for 100 million. However, I doubt anyone in history has reached the mechanical durability limits of 50 million key actuations so 100 million is superfluous.

Unfortunately, the KS-20 will require its own custom PCB. So you cannot retrofit older boards with the newer switch technology. On top of that, while the actuation force was described as 30-grams of force in the product guide, their actual force came out in the ballpark of 45-grams of force when I tested two switches. It could be that the magnetic switch, on the PCB, actually has a lower actuation force.


Gateron KS-12 Waterproof Switches

Unfortunately, Gateron did not show me their waterproof switch, which unfortunately requires its own specialized PCB. The switch contains four plastic stabilizers on its base, though, which means you cannot simply stick one on a random Cherry-MX compatible PCB. So if you wanted to spray a waterproof coating on your favorite PCB and throw some KS-12 switches on it, you’re out of luck.

Gateron 2019 Vs. Gateron 2020

Gateron’s older lines of keyboard switches included more or less copies of Cherry’s color scheme with their own unique take. These models (KS-3, KS-8, and KS-9) included the following colors:

  • Blue: midweight, 55g actuation, clicky
  • Brown: lightweight: 45g actuation, tactile
  • Black: midweight, 50g actuation, tactile
  • Red: lightweight, 45g actuation, linear
  • Green: heavy, 80g actuation, clicky
  • Clear: lightweight, 35g actuation, linear

Other than the KS-12, KS-21, and KS-20, there isn’t much new to announce. Many of its 2019 switches, like the Ink series, are not much different from its 2018 switches other than in aesthetics. Whiel there are many Gateron switches on the market, a few of the new products provided to me appear to be new options. It appears that Gateron issued updated switches of their KS-9 series and has more or less increased the bottoming-out force of some of its main switches. It also reissued these with different colored housing, mismatched against the color of the stem. The stem-color represents the actuation force and the housing color seems to indicate the bottoming-out force. Unfortunately the Gateron rep didn’t fully understand my questions regarding these new, unlabeled, products.

I did not see revisions of any other switches. For example, in 2019, Gateron announced an infrared switch, known as the KS-15. And it eventually added its Ink series, which was more or less colored, clear-bodied switch housings with slightly deeper actuation points. Neither line seems to have received an update.


Overall, Gateron’s 2020 lineup represents a more radical departure from its competitors and its 2019 offerings.

    Can you please share a link or some what to buy them?
    I really want to try browns

      Hi Israel, I'm sorry about not including a purchasing link. I have contacted the Gateron-US rep and asked him about it. I think the issue is that there are no PCBs that use the Gateron low profile switches.

    What's with switches being such a big deal? This is the third article, so people must want it.
    Mind you, I remember Speccy keys so knock yourselves out.

      People send more time with their keyboards than they do their loved ones. I found my old membrane keyboard was causing my fingers to swell a little from the constant pounding on keys. When I built a keyword it was in order to save my hands the stress of constant typing. I used lighter, quieter switches and it's great!

    "However, I doubt anyone in history has reached the mechanical durability limits of 50 million key actuations so 100 million is superfluous."

    Chuck Norris can, if he has a mind to. He will count backwards from 50 million and the manufacturers better make good on their promise.
