Core Advantages: The Ultimate Answer for Comfort & Aesthetics
We know you need more than just a switch that registers inputs. You need a reliable daily driver that lets your fingers completely relax, while flawlessly showcasing your keyboard's RGB aesthetic. The Starry Switch eradicates fatigue, harsh lighting, and scratchiness.
The Problem: Finger Fatigue & Mushiness
Standard linears (45-50gf) cause severe joint stiffness during marathon typing or coding. Conversely, basic ultra-light switches use weak springs, resulting in a mushy, sluggish rebound that ruins your typing rhythm.
The Problem: Harsh RGB Hotspots
Basic clear housings or generic light guide slots allow bottom LEDs to shine straight through. This creates harsh, glaring hotspots that make your expensive custom keyboard look cheap and uneven.
The Problem: Dust Failure & Scratchiness
Open-style cross stems easily trap dust and hair, causing metal contacts to oxidize and double-click (chatter). Unlubed factory switches also produce an annoying, sandy friction noise.
✨ Kailh Starry Switch: 37gf cloud force, Honeycomb RGB diffusion, and BOX sealed protection. The ultimate fatigue-free, visually stunning endgame.

This is a very common but unnecessary worry. While 37gf is incredibly light, the Starry Switch retains a standard 1.7mm pre-travel and ramps up to a ~48gf cushioned bottom-out. This progressive force curve prevents accidental presses if you simply rest your fingers on the keys, while drastically reducing muscle strain during actual typing. Most users call it the "absolute perfect balance for all-day office work."
Standard short springs feel mushy and have a sluggish, slow reset. The 20.5mm double-stage extended spring provides a much more stable and linear force curve on the downstroke. Most importantly, the moment you release the key, it provides an incredibly strong, crisp, and snappy rebound. This "light press, fast bounce" dynamic gives your typing a satisfying rhythm and kills any feeling of sluggishness.
Normal clear housings let LED light shoot straight through, creating harsh, blinding hotspots that make RGB look cheap and uneven. The Starry Switch features a unique hexagonal honeycomb optical texture. It acts like a premium softbox diffuser, perfectly shattering and scattering the direct light beam. The result is an incredibly even, soft, and rich ambient glow—like a dreamy starry night—massively elevating your desk aesthetic.
Absolutely not. The Starry switches come out of the box with Kailh's automated, high-precision factory pre-lubing, perfectly coating the rails and springs. Combined with the naturally slick modified POM stem, you get a buttery smooth, frictionless linear feel, completely free of scratchiness or spring ping right from day one.
Yes, you can! The two extra plastic legs on the bottom of the Starry switch provide extra stem stability and eliminate wobble on plateless PCBs. If your PCB only supports 3-pin switches, simply use nail clippers or flush cutters to snip off those two side plastic legs flat against the base. They will fit perfectly, and doing so will not void your warranty or affect the switch's functionality or its 80M lifespan in any way.
