Full-size mechanical keyboard with linear switches

The Logitech MX Mechanical is a full-size wireless keyboard built around low-profile linear switches that deliver uninterrupted key travel and minimal spring force for a smooth, responsive typing feel. It is designed for professionals who spend long hours at the desk and want a premium mechanical experience without the bulk of traditional high-profile switches. The metal top plate adds rigidity and a solid, premium feel.

Check OS compatibility and receiver requirements

Verify that your operating system is among the supported platforms: Windows, macOS, Linux, Chrome OS, iOS, iPadOS, or Android. The keyboard pairs with up to three devices via Bluetooth Low Energy or the included Logi Bolt USB receiver; note that it is not compatible with older Logitech Unifying receivers. On macOS, FileVault encryption may block Bluetooth input at the login screen, so the Bolt receiver is required for pre-boot authentication.

Battery life and illumination under daily use

A full charge of the 1500 mAh Li-Po battery lasts up to 15 days with backlighting active or up to 10 months with the backlight turned off; actual endurance varies with usage patterns. Smart illumination activates when your hands approach and adjusts brightness to ambient conditions, conserving power during sustained sessions. The keyboard recharges via USB-C, allowing quick top-ups without interrupting workflow.
