0-01Onyx Linear

Overview

Onyx is a medium-weight linear with a deeper voice. Nylon on both the top and the bottom housing soaks up the high frequencies that make a switch sound clacky, so each press lands as a low, rounded thock — deepest in a gasket-mount board with PBT keycaps.

It takes 55 gf to actuate and 65 gf to bottom out: a deliberate press that lets fingers rest on the keys without setting them off and takes the edge off heavy bottom-outs. Opaque black housings and a dark stem disappear under any keycap set and keep RGB to a soft glow around the keycaps.

  • 55 gf medium weight
  • Full nylon housings: deep, low sound
  • Opaque all-black look
  • Factory lubed

Force curve

How hard the key pushes back at every depth of the press, drawn through its measured actuation, peak and bottom-out forces. The dashed line is the way back up.

Force curve · Onyx Linear

Onyx Linear force curve. The key starts at 45 gf and rises evenly, with no bump. It registers at 2.0 mm with 55 gf and bottoms out at 4.0 mm with 65 gf. On the way up the force typically runs about 4 gf lower.

Bottom-out

Release

Drawn through the measured points in the spec table. The shape between them and the release line are typical for a linear switch, not a measurement of every unit.

Anatomy(4)

Four parts, each in its own plastic and colour. The materials decide much of the sound.
Onyx Linear — exploded view of the housings, stem and spring

  1. 0-01top housing

    Nylon

    Softer plastic that rounds off the sound into a deeper, fuller note. Closes the switch and guides the stem; shapes the sound of the upstroke.

  2. 0-02stem

    POM

    Self-lubricating: the smoothest stroke and a soft, creamy sound. The moving part. Its cross holds the keycap; with no bump legs, nothing interrupts the stroke.

  3. 0-03spring

    20 mm single-stage spring

    Sets the weight: how hard the key pushes back at the top and at the bottom of the stroke.

  4. 0-04bottom housing

    Nylon

    Softer plastic that rounds off the sound into a deeper, fuller note. Holds the metal contacts and pins; shapes the sound of the bottom-out.

Sound & feel

Linear switch with a thocky sound profile.

Sound profile

  1. Muted
  2. Creamy
  3. Thocky
  4. Poppy
  5. Clacky
  6. Clicky

Thocky. Deep and low, like a solid knock on wood.

Linear switches

Straight down and back up with no bump — the smoothest, most consistent stroke.

Feel
The spring’s force rises evenly from the first millimetre to the bottom. Nothing interrupts the stroke, so every press feels the same.
Sound
Set almost entirely by the plastics: nylon reads deep, polycarbonate bright and poppy, full POM soft and creamy.

Good for

  • Fast games and repeated taps
  • Smooth typing if you bottom out anyway
  • Your first custom build
  • Heavy hands, with a heavier spring

Think twice if: You want to feel the moment a key registers — a linear gives no signal until it bottoms out.

Keyboards it fits(2)

Any MX-style hot-swap keyboard takes these — no soldering. They do not work in magnetic (HE) keyboards.
Hot-swap
Sockets that let you pull and insert switches without soldering. Strata 75 and Flux TKL have MX-style hot-swap sockets; Halo 65 HE has magnetic (HE) hot-swap sockets — each takes only its own kind of switch.
3-pin vs 5-pin
5-pin switches have two extra thin plastic legs that steady them in boards without a plate. Hot-swap boards with 5-pin holes take both kinds; for a 3-pin-only board, clip the two plastic legs off with flush cutters — never the metal pins.

They fit any hot-swap keyboard with MX-style sockets, including our Strata 75, Flux TKL and Atelier builds. They have 5 pins, and our boards take them as they are. If your board only takes 3-pin switches, clip the two thin plastic side legs flush with a pair of flush cutters — never the metal pins. They do not work in magnetic (HE) keyboards, and a board without hot-swap sockets needs soldering to change switches.
