Gateron KS-3 series of keyswitches are clones of Cherry MX keyswitches. Unlike its successors: the KS-8 and KS-9 series, it supports only two-pin LEDs.

Description[edit | edit source]

The outer shapes and internals are virtually indistinguishable from Cherry MX except that the top is branded "Gateron" in an italic font. All parts should be interchangeable except for the leaf springs that perform the electric switching. Cherry leaf springs fit inside Gateron housings but Gateron leaf springs are slightly thicker and do not fit into Cherry MX bottom housings. The copper leaf springs have gold-plated cross-points.<ref name="hwood34" /> The cross-points were rotated 90° from MX internals on early revisions, but are oriented the same as Cherry MX on later revisions.

KS-3 housings can be black or translucent white. The translucent shell switches are always sold as PCB mount, while the single black shell variant found to date is plate mount. The fixing pins (for PCB-mounting) are somewhat wider than Cherry MX, giving a tighter fit.

The circle-shaped immersion that allows for LED mounting is slightly larger than compared to Cherry MX switches, which allows mounting standard 3 mm LEDs without having to sand off the flange

Switches with white sliders are very light and linear, with no Cherry MX equivalent. Cherry's similar-looking switches are instead tactile or clicky (older type).

Gateron's clicky switches lack the small pin on the top of the slider beside the cruciform mount that clicky varieties of Cherry MX and many clones have. This makes clicky Gaterons fit silencing clips whereas the others do not.

Custom switches[edit | edit source]

Zealio
The Zealio family of switches from Zeal PC. Some switches have been sold in translucent shells but most variants have had transparent shells similar to Gateron KS-8 series. The tactile variants have custom sliders, exclusive to Zeal PC. They have lubrication and gold-plated springs.
Linjär
Switches with linear (Swe:"Linjär", pron:"linnyair") feel, in the colours of the Swedish flag, with lubrication and gold-plated springs. Group run by Swedish enthusiasts in early 2019.


Key feel[edit | edit source]

The tactile/actuation point is slightly higher up than on the corresponding Cherry MX switch. The switches have been described as having smoother action than new Cherry MX but not as smooth action as vintage/broken-in Cherry MX.

The springs are slightly lighter than the corresponding Cherry MX, especially in starting force. The tactile bumps of tactile switches can feel slightly sharper, probably because of them being higher up in the stroke, the starting force from the springs being lighter and the leaf spring being slightly stiffer.

Availability[edit | edit source]

Packs of KS-3, as well as KS-8 and KS-9 are now available from multiple enthusiast stores.

Switches can come pre-installed in keyboards from:

Group orders for switches have been conducted on Massdrop and Geekhack. Various switches have also been for sale on Asian merchant forums, such as Taobao. Transparent housings have also been available separately for modding.
