Nintendo Switch 2 Joy-Con Mouse Functionality: Evidence and Speculation

Recent circumstantial evidence suggests the Nintendo Switch 2 Joy-Cons may offer a novel functionality: operation as computer mice. While the widespread adoption of this feature by game developers remains uncertain, it aligns with Nintendo's history of innovative controller designs.

The evidence originates from Vietnamese customs data obtained by Famiboards user LiC, who has previously uncovered information related to a suspected Nintendo parts supplier. This data, a source of numerous Switch 2 rumors, recently revealed references to polyethylene (PE) adhesive tape described as "mouse soles" and intended for "game console handles." The use of the term "mouse soles," typically referring to the bottom of a computer mouse, strongly implies mouse-like functionality.

Two "mouse sole" model numbers, LG7 and SML7, were identified. These designations are not found in public component databases, suggesting they are new, unreleased products. The listed size, 90 x 90mm, is large enough to cover the back of the Joy-Cons, likely requiring trimming during assembly.

Not a First for Handhelds

While innovative for Nintendo, 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 supplies a plastic housing to facilitate this mode. This, along with the Legion GO's magnetic controller rails—a feature also rumored for the Switch 2—suggests potential similarities between the two devices.
