The Altair 2 is an ultra-thin mechanical keyboard that measures just 4.75 mm. It is nearly 70% thinner than the previous Altair. The design goal was a slim keyboard with no compromise on typing feel, and the choices below show how it gets there.

The thin body starts with the key switch. The Altair 2 uses a new mechanical switch design that takes up very little space, and that saving is what makes the 70% reduction in thickness possible. For anyone shopping for a slim mechanical keyboard, the switch is the first thing to look at.

Asymmetric design and internal layout

Fitting a mechanical keyboard into 4.75 mm meant rethinking its internal architecture. The Altair 2 uses an asymmetric layout. A high-density power cell and a speaker sit in the battery casket, and other components are packed under the M dial plinth and the space bar, so little space goes unused.

Dual-layer inertial dampener for refined typing

Typing quality depends on sound and vibration as well as key travel. The Altair 2 has a dual-layer inertial dampener system that suspends the typing platform and isolates it from acoustic noise and vibration. The result is refined key feedback and better acoustics.

The M dial is magnetically detachable, clickable, and swappable. It gives you intuitive MIDI control, which is useful for music production and other creative software. Since the dial detaches, the keyboard is also easier to carry between desks, studios, and bags.

Night Light backlight for late-night work

Blue light is best avoided when you work at night, so the Altair 2 includes a warm red backlight called Night Light. It reduces eye strain and helps preserve your night vision, which makes long evening sessions more comfortable for anyone who works late.

Made for macOS

The Altair 2 is designed as a companion to macOS and comes with a native Mac app. A keyboard is the interface between a person and a computer, and close integration with the operating system keeps that connection smooth.

Who should consider the Altair 2

Mac users who want a portable, low-profile mechanical keyboard will find the most to like here. Musicians and producers get a built-in MIDI dial. Night owls get a backlight designed for dark rooms. Anyone who has avoided thin keyboards because of their typing feel gets a mechanical switch and a vibration-isolating platform in a 4.75 mm body.
