GravaStar – Mercury V75

Where Industrial Design Meets Acoustic Aesthetics, we engineer high-end peripherals that look as good as they perform. The Mercury V75 is our first magnetic switch keyboard, designed to redefine 75% layout standards with cutting-edge magnet technology, Gasket comfort, and RGB artistry.

80HE Sound Test

Hear the Mercury V75 HE difference.

The Mercury V75 HE delivers a refined acoustic signature—deep, satisfying "thock" at moderate volumes with crisp, responsive feedback. Swap switches or keycaps to dial in your perfect sound. No modding required.

True 8kHz Polling Rate

The V75 boasts a blazing 8000Hz USB polling rate, paired with 256kHz key-position scanning, delivering a True 8kHz polling experience that slashes keyboard latency to a near-instantaneous 0.125ms.

Precision Trigger, Rapid Response, Enduring Performance

GravaStar Customized HE Switches

Engineered for industry-leading 0.005mm precision and adjustable trigger depth (0.1mm- 3.5mm), they eliminate lag and keep you in control. Perfect for clutch plays in CS2, precise aiming in Valorant, or building a setup that stays sharp. This keyboard uses north-pole-down (N-pole down) Hall Effect switches and currently does not support south-pole-down (S-pole down) configurations.

Adjustable Actuation Point

Eliminate the slowest part of input lag: the initial key press travel before activation. With 0.1-3.6mm adjustable trigger depth (in 0.1mm increments), tailor each key to your playstyle—shallow presses for lightning-fast combos, deep presses for intentional precision. Perfect for reducing accidental taps and optimizing response times in fast-paced games.

Dynamic Rapid Trigger

Say goodbye to fixed reset points. This feature dynamically adjusts activation/deactivation points based on key travel distance, not predefined limits. Keys engage instantly on press and release immediately on release, enabling fluid, rapid-fire key repeats—ideal for gaming scenarios requiring split-second reactions (e.g., FPS aim, MOBA skill shots).

Last Keystroke Prioritization (LKP) + Snap Click

LKP ensures smooth directional changes by prioritizing your last-pressed key, critical for games like Valorant or Apex Legends. Snap Click intelligently resolves simultaneous key presses: it favors deeper presses and auto-resets shallower ones, so you never miss a command. Together, they eliminate "input chaos" and sharpen your competitive edge.

Rapid Trigger Mode

Rapid Trigger Mode eliminates key "stiction"—resetting keys instantly as they travel upward, so you can re-press and switch inputs faster than ever. No more waiting for keys to "bounce back"—execute rapid combos, skill shots, or direction changes with zero delay.

Semi-Aluminum Construction

Durability Meets Modern Design

GravaStar V75 blends rugged durability with sleek aesthetics through its innovative semi-aluminum construction: a sturdy metal frame forms the backbone, ensuring structural integrity even during intense gaming marathons, while a premium plastic base adds a lightweight, modern touch to your desk setup.

Hot-Swappable Design

Tailor Your Keyboard To Perfection

GravaStar V75’s hot-swappable magnetic switches let you redefine your typing experience—swap out worn switches or experiment with new feels without soldering. While our magnetic switches use advanced Hall Effect technology for precise actuation.

*Compatibility is limited to select TTC Switches and Gateron models (check our website for details).

5-Layer Acoustic Foam

Silence Meets Sensation

GravaStar V75’s enhanced acoustic foam system minimizes keystroke vibrations—delivering a crisper, more satisfying sound and a smoother typing feel. Whether you’re crushing FPS combos or typing up reports, this multi-layer design ensures every press feels deliberate, every click stays quiet, and your focus stays sharp.
