Emerging circumstantial evidence suggests the Nintendo Switch 2 Joy-Cons could offer a novel functionality: acting as computer mice. While the widespread adoption of this mode by game developers remains uncertain, the feature aligns with Nintendo's history of innovative experimentation.
The evidence originates from Famiboards user LiC, who previously accessed Vietnamese customs data related 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: shipping manifests mentioning polyethylene (PE) adhesive tape described as "mouse soles" and intended "to stick to game console handles." This terminology, typically associated with computer mice, hints at potential mouse-like functionality in the Switch 2 Joy-Cons.
Two "mouse sole" model numbers, LG7 and SML7, were referenced. These numbers haven't been found in public component databases, suggesting they might be new, unreleased products. The reported 90 x 90mm size of the tape pieces seems large enough to cover the entire back of the Joy-Cons, potentially requiring trimming during assembly. The validity of LiC's information, however, remains unconfirmed.
While a mouse-like controller mode is consistent with Nintendo's experimental approach, it's not unprecedented. The Lenovo Legion GO, released in 2023, already features this capability with its right controller, transformable into a mouse when rotated sideways. Lenovo even supplies a plastic piece to facilitate smoother surface movement in this mode.
The Legion GO also incorporates magnetic rails for controller attachment, a feature also rumored for the Switch 2. Therefore, the Legion GO might offer a preview of Nintendo's hybrid console evolution.
