"Low profile" is a height class, not a switch type. Everything you know about linear/tactile/clicky still applies — what changes is the physical envelope, and with it the sockets, keycaps and cases it can live in.
| Kailh Choc (V1/V2) | MX-style LP (NuPhy/Lofree/Gateron KS-33 class) | |
|---|---|---|
| Stem | Smaller Choc cross | MX-style cross (LP height) |
| Keycaps | Choc-specific sets only | Dedicated LP sets (LP-MX-shaped) |
| Pin spacing | Choc spacing | LP-MX spacing |
| Typical boards | Ortho/split/custom LP builds | NuPhy Air, Lofree Flow, Keychron low-profile lines |
| Travel (typ.) | ~1.4–1.5 mm actuation, 2.7–2.8 mm total | ~1.2–1.7 mm actuation, 2.6–3.0 mm total |
The #1 LP buying mistake: buying "low-profile keycaps" for a Choc board. Choc stems are physically smaller than LP-MX stems — the two LP worlds do not share caps. The checker separates these when you pick a Choc switch.
