Compact 75% Hall Effect keyboard

The Vszerda Mercury V75 HE uses Hall Effect magnetic switches with a 0.005mm sensitivity and adjustable actuation between 0.1mm and 3.6mm. A 75% layout provides 79 keys including a full arrow and function row. It connects via a wired USB-C interface and features per-key RGB backlighting.

Sustained 8000Hz polling performance

An 8000Hz polling rate delivers a 0.125ms response time that remains consistent during extended gaming sessions. Hot-swappable switch sockets allow worn switches to be replaced without soldering, maintaining the original feel over time. Software lets you tune actuation points and macros for each key individually.

Aluminium chassis thermals and power

The semi-aluminium Mecha Gray chassis dissipates heat from the PCB during long periods of rapid keystrokes. Wired USB-C power draw stays within standard bus limits so no external adapter is required. Mechanical linear switches produce a consistent acoustic profile without rattling stabilisers.

Questions about this item

How much power does the 8000 Hz polling rate draw during all-day use?

The keyboard draws power over its wired USB-C connection; the 8000 Hz polling rate and 0.125 ms response time operate within standard USB power limits.

What software or operating system is needed to adjust the 0.1–3.6 mm actuation points?

GravaStar software runs on Windows and lets you set actuation points per key, create macros and control RGB lighting for the 79-key layout.

Will the 75 % layout and Hall Effect switches work with my older PS/2-to-USB adapter?

The board uses a native USB-C interface; a passive PS/2 adapter will not work — use a USB-C port or a USB-C-to-USB-A cable instead.
