GravaStar UFO Mechanical Switch

The All-Around Esports Linear: Skeletal UFO Sci-Fi Architecture Meets Pure HIFI Mahjong Thock.

Are you tired of traditional boxy switches that sound hollow and wobble off-center when gaming at breakneck speeds? GravaStar tears down traditional design conventions with the exclusive "UFO Mechanical Switch".

Inspired by sci-fi skeletal starships, it fuses an open-chassis 360° circular anti-wobble rail with a walled POM stem, an independent acoustic sealed bottom chamber, and an integrated high-transmittance optical light pillar. Delivering a balanced 40gf actuation and a 23mm extended recoil spring, it ensures rapid tactical response alongside an addictively concentrated, solid "Mahjong tile" bottom-out acoustic signature.

Core Advantages: Engineering The Ultimate All-Rounder

Standard mechanical switches force compromises between wobbly off-center presses, hollow spring rattles, or sluggish return springs. The GravaStar UFO switch eliminates all three.

The Problem: Lateral Keycap Wobble

Conventional cross-stems suffer from loose mold tolerances. Pressing keycaps off-center generates significant tilt, creating inconsistent friction that disrupts typing cadence.

The Problem: Hollow & Clacky Echoes

Thin, unsealed switch housings allow acoustic frequencies to scatter inside the switch bottom, producing a cheap, high-pitched clack accompanied by irritating spring ping.

The Problem: Sluggish Reset & Fatigue

Traditional short springs create either a heavy, tiring actuation or a lazy, mushy reset, causing missed inputs during fast-paced competitive esports combos.

🛸 The GravaStar Solution: 360° circular dual-rail stability, sealed acoustic chamber for deep HIFI Mahjong sound, and a snappy 23mm extended spring for effortless speed.
GravaStar UFO Skeletal Architecture & 360 Degree Dual-Rail Stem

Sci-Fi Skeletal Architecture
360° Circular Dual-Rail Zero-Wobble Stem

The Solution

Breaks away from traditional square enclosures by adopting a futuristic, skeletonized UFO saucer upper housing crafted from smoked-translucent Polycarbonate, reinforced by a 360° circular perimeter and walled POM cross-stem.

The Benefit

Enjoy rock-solid keypress precision. The circular dual-rail design completely locks down lateral play, guaranteeing that whether you strike the dead center or the very edge of the keycap, the switch glides downwards in a true vertical trajectory with zero rattle.

GravaStar UFO Sealed PA66 Bottom Acoustic Cavity

Pure Acoustic Focus
Sealed Bottom Chamber for HIFI Mahjong Thock

The Solution

Constructed with an upgraded PA66 high-density nylon base plate engineered with a fully sealed, acoustic-converging bottom cavity, eliminating hollow internal voids.

The Benefit

Turns every typing session into an addictive sensory ritual. The sealed chamber traps and rounds out high-frequency vibrations, projecting an incredibly concentrated, deep, and crisp sound reminiscent of solid Mahjong tiles gently clacking against hardwood.

GravaStar UFO 23mm Extended Spring and Optical Light Pillar

Agile 40gf Balance
23mm Extended Spring & Optical Light Guide

The Solution

Calibrated with a 40gf feather-light actuation and 50gf bottom-out driven by a 23mm high-elasticity extended spring, paired with an integrated optical-grade light guide pillar.

The Benefit

Experience zero-fatigue high-speed gaming. The extended spring pre-loads tension to deliver instantaneous, snappy rebound that never feels mushy, while the dedicated light pillar channels underlying PCB RGB cleanly through keycap gaps without blinding glare.

"That Mahjong Thock sound is 100% real."

"I put these on my aluminum custom board. The sound profile is ridiculously good right out of the box—super deep, zero spring ping, and that pure marble/mahjong clack. You don't even need to hand-lube them."

— @ThockEnthusiast, Custom Keeb Builder
★★★★★

"40gf with the 23mm spring is the sweet spot."

"A lot of light switches feel mushy when returning. The 23mm spring in the UFO switch pushes back immediately, making fast counter-strafing in FPS games feel super crisp. Zero keycap wobble on my wide modifier keys too."

— @ApexVanguard, Competitive FPS Player
★★★★★

"Aesthetic desk setup centerpiece."

"The smoked translucent UFO design looks incredible under RGB lighting. The built-in light pillar diffuses light evenly across my pudding keycaps with no ugly hot spots. GravaStar nailed the futuristic mecha vibe."

Frequently Asked Questions

Q Is this switch compatible with standard mechanical keyboards?
Yes! Unlike Hall Effect (magnetic) switches, this is a standard contact-leaf mechanical switch. It uses a standard 5-pin MX footprint that fits directly into any standard 5-pin or 3-pin (by clipping the two plastic guide pins) hot-swappable mechanical keyboard PCB. It works with conventional mechanical keyboards from brands like Keychron, Epomaker, Royal Kludge, Akko, etc.
Q How does the "Sealed Bottom Chamber" create a Mahjong Thock sound?
Traditional switch housings leave open gaps beneath the contact leaf and center pole, causing sound waves to leak and bounce around randomly inside the keyboard case. The GravaStar UFO switch seals this acoustic boundary with high-density PA66 nylon. This acts as an acoustic compressor that gathers sound waves during bottom-out, suppressing hollow echoes and projecting an authoritative, deep "Thock" sound signature.
Q Do I need to manually lube these switches after receiving them?
No manual lubing is needed. The UFO switches feature automated factory precision lubrication applied to the POM stem rails and guide points. Combined with the natural low-friction self-lubricating characteristics of the POM core, the switches are completely buttery smooth right out of the box with zero scratchiness.
Q How does the 23mm extended spring feel compared to standard switches?
Standard switches use short 14mm-16mm springs that start with low resistance and suddenly ramp up. The 23mm extended spring is already pre-compressed inside the housing. This provides a wonderfully linear, consistent resistance from the moment your finger touches the key, followed by an aggressive, energetic upward rebound that ensures fast double-taps and zero finger fatigue during long gaming or coding sessions.
Q Will the smoked translucent upper housing dim my RGB lighting?
Not at all! The switch incorporates an optical condenser light guide pillar positioned directly over the SMD LED location. This acts like a light pipe, gathering illumination from the PCB and projecting it upward through the keycap legend evenly, while the smoked skeletal body provides a subtle, premium cyber aura around the base.
