Emerging circumstantial evidence suggests the Nintendo Switch 2 Joy-Cons might offer a novel functionality: acting as makeshift computer mice. While the practicality of this mouse-like controller mode for game developers remains uncertain, it aligns with Nintendo's history of innovative experimentation.
The intriguing evidence comes from Famiboards user LiC, known for uncovering Vietnamese customs data linked to a suspected Nintendo parts supplier. This data source has fueled numerous Switch 2 rumors since mid-2024.
In early January 2025, LiC revealed further findings: customs manifests mentioning polyethylene (PE) adhesive tape, described as "to stick to game console handles," and labeled as "mouse soles." This terminology, typically associated with computer mice, hints at potential mouse functionality for the Switch 2 Joy-Cons.
LiC identified two "mouse sole" model numbers: LG7 and SML7. These designations haven't been found in public component databases, suggesting they represent unreleased products. The data indicates both tape pieces measure 90 x 90mm, potentially large enough to cover the entire back of the Joy-Cons, though likely requiring trimming during assembly.
While unconventional, a mouse-like controller mode isn't unprecedented. The Lenovo Legion GO, released in 2023, features a right controller that functions as a mouse when rotated sideways. Lenovo even includes a plastic piece to enhance its gliding ability on surfaces.
The Legion GO also boasts magnetic rails for attaching controllers, a feature rumored for the Switch 2. This similarity further strengthens the parallels between the two devices.
