GravaStar - Mercury V75 Lite Onyx Crystal HE Keyboard
GravaStar – Mercury V75 Lite
The Mercury V75 Lite magnetic keyboard redefines 75% layouts with cutting-edge magnetic technology, Gasket comfort, and striking RGB lighting.
Custom GravaStar HE switches
Dominate every match with an ultra-fast 8000 Hz polling rate and near-zero 0.25 ms latency. Equipped with Custom GravaStar HE switches, 0.01 mm RT precision, and a 5-layer acoustic construction. Customize 16 RGB effects via the Web Driver — your complete competitive arsenal.

Adjustable actuation point
Eliminate the slowest element of input latency: the initial key travel before activation. With an adjustable actuation depth of 0.1–4.0 mm (in 0.1 mm increments), you can tailor every key to your playstyle — shallow presses deliver lightning-fast combos, while deeper presses provide deliberate precision. The perfect solution for reducing accidental presses and optimizing reaction time in fast-paced games.

Dynamic Rapid Trigger
Say goodbye to fixed reset points. This feature dynamically adjusts actuation and deactivation points based on key travel distance rather than preset limits. Keys activate instantly when pressed and reset immediately when released, enabling smooth, lightning-fast repeated presses — ideal for gaming situations requiring split-second reactions (e.g. aiming in FPS games, using abilities in MOBA games).

Last Key Prioritization (LKP) + Snap Click
LKP ensures smooth directional changes by prioritizing the last pressed key — crucial in games such as Valorant and Apex Legends. Snap Click intelligently resolves simultaneous key presses: it favors deeper presses and automatically resets shallower ones, so you never miss a command. Together, they eliminate “input chaos” and strengthen your advantage over opponents.

Rapid Trigger Mode
Rapid Trigger Mode eliminates key “sticking” — it resets keys instantly during upward movement, allowing you to press them again and switch inputs faster than ever. No more waiting for keys to “bounce back” — execute quick combos, use abilities, or change direction without any delay.

Magnetic precision and durability
Make flawless plays with an exceptionally light 35 gf initial force and a 15.5 mm spring with dynamic characteristics. A precise 500 GS magnetic flux delivers true, lag-free inputs. A lifespan of 100 million clicks gives you total control and lets you outlast the competition.
Customization and freedom
Adjust the tactile feel in seconds. The fully hot-swappable PCB lets you effortlessly replace switches without soldering. Create your ideal personalized gaming keyboard and instantly adapt it to any competitive style.


Silence and satisfaction
An aluminum plate combined with multi-layer PORON and IXPE foams eliminates all hollow echoes. The stable silicone base ensures that every press delivers a crisp, focused premium “thock” sound, letting you play without distractions.
Unmatched RT precision
Achieve flawless counter-strafes with astonishing 0.01 mm Rapid Trigger (RT) precision. This hypersensitive actuation responds to your microscopic movements, eliminating input latency. Outsmart opponents instantly with response speed tuned to the absolute limit.


Control core
The intelligent brain behind the speed. It coordinates every input with absolutely zero latency, ensuring uncompromising control and the ultimate competitive edge.
Ergonomics and durability
Dominate marathon sessions effortlessly. The ultra-low, contoured 19 mm front profile and rounded edges naturally position your wrists. Eliminate tension and enjoy continuous, fatigue-free comfort during endless gaming or typing.


Aura and action
Illuminate your setup with a stunning RGB spectrum featuring 16 million colors. Enhanced by an ultra-transparent case, it creates a deeply immersive cyberpunk aesthetic. Customize the dynamic lighting to match your style and dominate the battlefield with absolute flair.
Control and convenience
Master your setup without unnecessary software. The browser-based Control HUB WEB seamlessly synchronizes your GravaStar peripherals. Instantly customize macros, RGB lighting, and precise actuation points — simply change the settings, save, and dominate.
