KS-27-RED
ActifGateron KS-27 Low Profile Red Linear
Gateron KS-27 low-profile switch — Gaterons entry into slim keyboards.
Applications courantes
Gaterons answer to Kailh Choc. Proprietary low-profile mount (not Choc compatible). Used in Nuphy Halo, Keychron K5 Pro, and other slim mechanical keyboards. 3.5mm total travel. Factory lubed.
Research Notes
1. Overview
The Gateron KS-27 Red is a low-profile linear mechanical keyswitch — part of Gateron's KS-27 low-profile family with an 11.75 mm housing height that shaves overall keyboard thickness versus full-size switches. It's a light red linear (~45 g) with short travel (≈1.5 mm pre-travel, ≈2.5 mm total) for a fast, smooth keypress. Gateron offers the KS-27 in Red (linear), Brown (tactile), and Blue (clicky). It uses Gateron's low-profile footprint (not MX spacing).
2. User Sentiment
Chosen for slim, low-profile keyboard builds where height and a fast light linear matter. Reviewers note the smooth travel and low profile; the main trade-offs are the short total travel (an adjustment coming from MX) and the low-profile-specific PCB/keycap ecosystem (KS-27 vs the taller KS-33, and vs Kailh Choc — they are not cross-compatible). Compared with Kailh Choc, the KS-27 is a competing low-profile standard.
3. Real-World Applications
Thin/portable mechanical keyboards and low-profile custom builds prioritizing a slim deck and quick light actuation; laptops-style typing feel with mechanical switches.
4. Technical Specifications
- Type: Low-profile linear
- Stem/color: Red
- Actuation force: ~45 g
- Travel: ≈1.5 mm pre-travel, ≈2.5 mm total (low-profile short throw)
- Housing height: 11.75 mm (KS-27 low-profile family)
- Rated life: ~50–70 million actuations (per Gateron listing)
- Footprint: Gateron KS-27 low-profile (its own PCB/keycap spacing — not MX, not Choc)
5. Ordering & Compatibility
Sold by Gateron and keyboard specialists in packs. Requires a KS-27-compatible low-profile PCB and keycaps — it is not interchangeable with MX, Kailh Choc, or Gateron's taller KS-33 low-profile. Confirm the board targets KS-27 before buying. Family: KS-27 Red (linear) / Brown (tactile) / Blue (clicky).
6. Known Issues
No major reliability issues. The key gotchas are ecosystem fit — KS-27 has its own low-profile footprint (distinct from MX, Choc, and KS-33) — and the short travel, which some MX users find takes adjustment.

Référence rapide d'installation
Panel cutout: 22mm. Insert from the front of the panel, secure with mounting nut from behind (tighten to 2-3 Nm).
Contact block: Snap or screw the contact block onto the rear of the button body. Ensure the contact block orientation matches the wiring diagram — NO terminals are usually marked.
Wiring: Use 0.5-2.5mm² stranded wire with ferrules. Tighten screw terminals to 0.8 Nm. Test the button function before energizing the circuit.

Dépannage
Button doesn't respond when pressed
Check the contact block first — it's the most common failure point. Test continuity across the NO or NC terminals with a multimeter. If no click is felt, the return spring in the head may be broken.
Works intermittently
Contact block contacts are pitted or burned. Replace the contact block — don't try to file the contacts. Check if the rated cycle count has been exceeded.
Button feels mushy or doesn't click
The spring return mechanism in the button head is worn. Replace the head. The contact block can usually be reused if it tests OK.
