Linear Switch

Linear switch provides a smooth and uninterrupted keystroke from top to bottom. They deliver consistent resistance throughout the entire keypress, creating a clean and fluid typing experience.

What Is A Linear Switch

Linear switches have a smooth keystroke from top to bottom with no tactile bump or click. They usually sound clean and consistent, ranging from deep “thocky” to sharper “clacky” depending on materials. Because they are smooth and fast, they are commonly used for gaming/Typing and by users who prefer uninterrupted keypresses.

Linear Switch Spring Weight & Actuation Force: How to Pick

Every linear switch has two force numbers worth knowing. Actuation (operating) force is how hard you press before the keystroke registers, and bottom-out force is how hard you push to hit the bottom of the keystroke. Since linear switches have no tactile bump, the spring weight is the single biggest factor in how a switch feels day to day.

Light (≈35–45g actuation / ~40–45g bottom-out)

Light linear switches feel fast and effortless, with very little resistance under your fingers. They're the go-to for gaming, where quick, repeated key presses matter, and for fast typists or anyone doing long sessions who wants to avoid finger fatigue. The trade-off: lighter springs are easier to trigger by accident if you rest your fingers on the keys.

Medium (≈40–50g actuation / ~45–55g bottom-out)

Medium-weight linears are the all-rounders and the easiest first switch to recommend. They balance speed with enough resistance to keep accidental presses in check, making them comfortable for mixed typing and gaming. The HMX Azalea (42–45g actuation, offered in 50g and 55g bottom-out) is a good example of this balanced, everyday feel. If you're not sure where to start, a medium linear is the safe pick.

Heavy (≈55g+ actuation / ~60g+ bottom-out)

Heavier linear switches ask for a more deliberate press and give you more control, which suits heavy-handed typists who tend to bottom out hard and anyone who wants to slow down their keystrokes for accuracy.

Quick guide: chasing speed for gaming → go light. Want one switch that does everything → go medium. Prefer control and a firmer, deeper feel → go heavy. Use the spring-weight options on each product page to fine-tune, and check the spec table for the exact actuation and bottom-out force.

Linear Switch Housing & Stem Materials: How They Shape Sound

Stems

  • POM / strengthened POM / LY — The harder the stem, the louder and clackier the switch. Standard POM gives a smooth, clacky sound; strengthened or ceramic-reinforced POM pushes it even louder and crisper. LY behaves similarly. These are the go-to stems for a bright, high-pitched, clacky linear.
  • UPE / soft "T-series" or U-series stems — Softer materials absorb energy instead of reflecting it, giving a thockier, deeper, quieter, more "creamy" sound.

Bottom housing

  • PA66 / Nylon with fiberglass — Adding fiberglass stiffens the housing and makes the switch louder, clackier, and higher-pitched. More fiberglass = thinner and sharper; less or none = fuller and rounder, leaning thockier.
  • PA12 — A softer housing material that, paired with a soft stem, produces the rare deep-and-quiet linear sound.
  • PC - A stiff material that would make bottom out sound very bright and clacky, but not too loud.
  • POM - Not too soft and not too stiff. Great for creating a balanced mid pitch sound

Top housing

  • PC (Polycarbonate) — Hard and clear, it reinforces a bright, sharp, clacky signature.
  • PA66/PA66 with fiberglass - The secret sauce to create a bright, crispy, and clacky top out sound
  • PA12 - Relatively softer material which is the best for a thocky and creamy sound.
  • POM - Not too soft and not too stiff. Great for creating a balanced mid pitch sound

Quick guide: want loud and clacky? Look for strengthened POM or LY stems with fiberglass-reinforced PA66/nylon housings. Want deep and thocky? Look for soft UPE/T-series stems with low-fiberglass nylon or PA12 housings.
