Nintendo Switch 2's C Button: A Strange Function Revealed [UPDATE]

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 C button rumored to be featured on the Nintendo Switch 2 might serve chat-related functions, according to a newly surfaced report. This revelation could provide clarity on one of the most intriguing aspects of Nintendo's next console.

Since late 2024, leaks about the Switch 2 have been rampant, with industry insiders believing these leaks stem from the console's entry into mass production around that time. These unofficial glimpses of the upcoming device consistently show an additional button, marked with a dark gray "C," located on the right Joy-Con just below the home button. Until now, the purpose of this mysterious button remained unknown.

Recent datamining efforts focused on the latest version of the Switch OS have led to a theory about the C button's function. A report from a burgeoning Discord server dedicated to the Switch 2 suggests that Nintendo's new firmware includes references to a feature code-named "Campus." This feature is believed to support group and voice chat for Nintendo Switch Online subscribers.

Nintendo Switch 2 Will Reportedly Support Screen Sharing

The same source indicates that Campus will facilitate screen sharing and chat groups for up to 12 users. Although the codename starts with a "C," if this feature relates to the new button on Nintendo's next console, the "C" likely stands for "chat" rather than "Campus." This development challenges the popular fan theory that the C button might enable casting the Nintendo Switch 2 screen to other devices.

Chat Support Isn't Exactly in Line With the Switch's Kid-Friendly Design

Given that group and voice chats require internet connectivity, it's probable that, if implemented, the Switch 2 would reserve such features for NSO subscribers. However, this remains speculative, especially considering the original Switch's deliberate move away from such functionalities. By omitting chat features, the Switch maintained a more kid-friendly environment. Reintroducing something akin to the Miiverse text chat could potentially raise concerns about online safety that Nintendo might prefer to avoid.

Whether the much-anticipated console truly features a C button—and what its purpose is—may soon be revealed. According to multiple sources, the official announcement of the Switch 2 is scheduled for this Thursday, January 16.
