Gateron Milky Yellow Pro V2 vs KS-9 Yellow

Trying to choose between two of the most popular budget-to-mid linear switches? The Gateron Milky Yellow Pro V2 and the Gateron KS-9 Yellow are both excellent daily drivers, but they have noticeably different sound and feel profiles.

Very short version: Milky = deeper/more muted and more relaxed, KS-9 = tighter/more stable and more RGB-friendly.

Quick answer (fast pick)

Choose Milky Yellow Pro V2 if your priority is a quieter, deeper “thocky” vibe.
Choose KS-9 Yellow if you want maximum stock stability and better RGB/SMD compatibility.

1. Positioning & build

  • Type: Linear (both)
  • Lubing: Factory-lubed (both)
  • Milky Yellow Pro V2 housing: full nylon (milky)
  • KS-9 Yellow housing: transparent top + nylon bottom
  • Tolerance feel: KS-9 often feels slightly tighter with less perceived play

2. Real-world sound & feel

Milky Yellow Pro V2 usually gives a deeper, rounder, and more muted sound profile. The keypress feels smooth and forgiving, which is great for relaxed long sessions.

KS-9 Yellow often sounds cleaner and a bit brighter, with a slightly tighter keyfeel. The return can feel “cleaner” and more controlled stock, especially if you are sensitive to wobble.

3. RGB / LED compatibility

  • Milky Yellow Pro V2: good, but less light transmission due to its milky/full-nylon character.
  • KS-9 Yellow: generally better for RGB/SMD thanks to the transparent top and more LED-friendly construction.
