KAILH Low Profile Choc V2 Keystem DIY MX Switches (30pcs, Red) Review (2026)

Who should consider these switches

These switches are aimed at builders working on a compact split or macro pad keyboard who already own a drawer of standard MX keycaps and do not want to buy a separate Choc keycap set. Because the keystem design swaps the usual flat Choc top for an MX compatible stem, any Cherry profile or OEM profile keycap snaps on directly, which keeps a DIY build's cost down and lets you keep a consistent look across a desk with multiple boards. This makes the most sense for someone building or upgrading a small split keyboard, like a Corne or similar kit, where a slim switch is wanted but a full Choc keycap wardrobe is not appealing. Builders chasing the thinnest possible profile with dedicated low profile caps should look at standard Choc stem switches instead.

How the switch feels and what is inside

Being a red variant, this is a linear switch, meaning the keypress moves smoothly from top to bottom without a tactile bump or click, which keeps typing sound low for shared spaces. Kailh's Choc V2 line generally operates in the low 40 gram force range with a shorter total travel than a standard height MX switch, which is part of what gives low profile boards their snappier feel. The pack includes 30 switches, enough for a compact 30 to 40 percent split keyboard build or a smaller macro pad, though larger 60% or 65% projects will need to combine multiple packs. The keystem itself is the notable design choice here, an adapter built into the stem so MX keycaps seat on a switch that is otherwise built to the Choc footprint.

Fitting them into a build

Before ordering, confirm the target PCB or hot swap plate is built for Choc V2 sockets specifically, since Choc V1 and V2 use different pin spacing and are not interchangeable, a detail that trips up first time builders more than any other step. Once seated, day to day use is straightforward, these are standard hot swap switches that pull out with a switch puller if you want to test different weights or brands later. Because the keystem raises the stem to MX height, the low profile benefit shrinks once a tall MX keycap goes on top, so builders chasing the flattest possible board should pair these with low profile keycaps instead. Keeping the switches dust free with occasional compressed air is the main care step, same as any exposed mechanical switch.

How this pack compares

Against Kailh's own Choc V2 Unmute tactile switches, this red keystem pack trades the tactile bump for a smoother linear feel, a matter of preference rather than one being objectively better. The plain Choc Low Profile Red 1350 pack, without the keystem, keeps the true low profile height and works if you are willing to buy Choc specific keycaps, which will feel flatter on the desk than this keystem version once built. Compared with a standard Kailh Choc White clicky switch, also sold in a 30 count pack, these reds are the quieter option, better suited to shared workspaces where the sharp click of a white switch would stand out.

Verdict

For builders who want the flexibility of standard MX keycaps on a slim split keyboard project, this keystem pack solves a real compatibility problem, matching our score of 7.8 out of 10 for a build and materials quality that holds up well for a linear switch pack. Just budget for the fact that the low profile advantage narrows once a full height keycap sits on top, and double check that your PCB is built for Choc V2 rather than the older V1 pin layout before ordering. Anyone chasing the thinnest possible board should look at Choc specific keycaps and stems instead of the keystem adapter design.
