A brand new teardown of Logitech’s latest mouse affords an enchanting have a look at the “Magspeed” scroll wheel used within the MX Master 3. The teardown, which was completed by the enterprise capital agency Bolt, additionally explores the myriad ergonomic and design modifications Logitech made to its flagship mouse as the corporate continues to refine and iterate after 30 years within the enterprise.
The major focus of the teardown is the mouse’s scroll wheel, which Bolt describes as being a “magnetic marvel.” The wheels in MX Master collection mice have at all times been capable of change between a step-by-step ratcheting scroll and free-spinning modes. The distinction with its third-generation MX Master mouse is that relatively than utilizing a motor and a mechanical contact to realize this impact, the mouse makes use of magnets which can be energized and de-energized utilizing small spikes of electrical energy. The scroll wheel then spins otherwise, relying on the state of the magnet inside.
Bolt says there are quite a few advantages to this new technique. Since there’s now nothing in mechanical contact with the wheel, there’s much less that’s going to wear down over time. The new mouse may also change in a short time between its two scrolling modes, as a result of there aren’t any mechanical elements that want to maneuver through the transition. Finally, the entire scroll wheel subassembly is way smaller than what could be discovered contained in the MX Master 2S.
As properly as analyzing the scroll wheel in forensic element, the teardown additionally appears to be like on the different refinements made with the mouse. These embody its newly redesigned thumb buttons, PCBs, and what Bolt calls its “impressive light pipe design.” If you’re focused on product design, then the whole teardown is properly value a learn.
