Nintendo accidentally confirmed the Switch 2‘s mystery button is a “C” Button, in some promotional material for the company’s new Nintendo Today app on the Google Play store. The reveal happened after the March 2025 Nintendo Direct, during which Nintendo also announced virtual game cards and showcased Metroid Prime 4 again. Twitter and Bluesky user Wario64 first spotted it and posted a zoomed-in version of the image to make viewing it easier.
We speculated about the nature of the mystery button shortly after Nintendo revealed the Switch 2 at the start of the year. At the time, it was just a blank square situated under the “Home” button on the right Joy-Con. It’s roughly where the invisible NFC detector is on the original Switch, the tool that scans Amiibo. Given that the Switch 2 is slightly larger than its predecessor, it looks like there’s still room for an NFC scanner even with the mysterious “C” button.
Granted, we still don’t know what the button actually does. The last Nintendo console with a “C” button was the Nintendo 64, which had four of them–a set of four buttons roughly where “ABXY” is on the current Switch. Wario64’s replies were full of suggestions about what the “C” might stand for, and while most of them were lewd, one seems like a reasonable fit: Cursor. If the Switch 2 lets users imitate a mouse with the Joy-Con, as Nintendo suggested in the console’s reveal trailer, perhaps the “C” button is what tells the Switch 2 to change how it registers Joy-Con inputs.
Whatever it does, we don’t have much longer to wait before we find out. Nintendo is hosting another Direct devoted to the Switch 2 and its game launch plans on April 2, 2025.
