Updated on January 14: The original version of this article linked to a different Discord server, also called "Nintendo Switch 2." The link has been changed to reflect the real source of the datamining effort. The original story is as follows.
Summary
- The Nintendo Switch 2's rumored C button may be used for chat functionality.
- Recent datamining efforts suggest the Switch 2 will support a group and voice chat feature code-named Campus.
- The next Nintendo console will reportedly be officially revealed on January 16.
The Nintendo Switch 2's rumored C button may serve a chat-related purpose, according to a recent report. This revelation could provide crucial insights into one of the most intriguing aspects of Nintendo's upcoming console.
Since late 2024, the Nintendo Switch 2 has been the subject of numerous leaks, largely attributed to the console's entry into mass production around that time. These leaks consistently show the new console featuring an additional button labeled with a dark gray "C," located on the right Joy-Con just below the home button. However, until now, the function of this mysterious button remained undisclosed.
Recent datamining efforts, detailed in a report from a dedicated Discord server focused on the Switch 2, have unearthed references to a feature code-named "Campus" within the latest Switch OS update. This feature is believed to be linked to group and voice chat capabilities for Nintendo Switch Online subscribers.
Nintendo Switch 2 Will Reportedly Support Screen Sharing

The same source indicates that Campus will enable screen sharing and support chat groups of up to 12 users. Given its codename starts with a "C," it's plausible that the C button on the Switch 2 relates to "chat" rather than "Campus," debunking the popular theory that it might be used for screen casting.
Chat Support Isn't Exactly in Line With the Switch's Kid-Friendly Design
Introducing group and voice chat features would necessitate internet connectivity, likely reserved for NSO subscribers. However, this move could contradict the kid-friendly ethos established with the original Switch, which deliberately avoided such functionalities to maintain a safer environment. Reintroducing features like Miiverse text chat might raise concerns about online safety that Nintendo may wish to avoid.
The true purpose of the C button on the Nintendo Switch 2, if it exists, may soon be revealed. Multiple sources indicate that the console will be officially announced on January 16.
