Nintendo Switch 2's C Button: A Weird Function Revealed [UPDATED]

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 mysterious C button rumored to be featured on the Nintendo Switch 2 might just be dedicated to chat functionality, according to a recent report. This revelation could illuminate one of the most intriguing aspects of Nintendo's upcoming console hardware.

Since late 2024, leaks about the Nintendo Switch 2 have been surfacing frequently, suggesting the console is now in mass production. These leaks consistently show an additional button on the right Joy-Con, marked with a dark gray "C" and located below the home button. However, the function of this button has remained a mystery—until now.

Thanks to dedicated datamining efforts on the latest Switch OS, a theory about the C button's purpose has emerged. A report from a burgeoning Discord server focused on the Switch 2 reveals that the new firmware contains references to a feature code-named "Campus." 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, with chat groups supporting up to 12 users. If Campus is indeed connected to the C button, it's more likely that the "C" stands for "chat" rather than "Campus." This debunks the popular fan theory suggesting the button might be used for casting the Switch 2's screen to other devices.

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

Introducing group and voice chat, which requires internet connectivity, would likely be limited to Nintendo Switch Online subscribers if implemented on the Switch 2. However, this move seems at odds with Nintendo's previous efforts to prioritize a kid-friendly environment by omitting such features on the original Switch. Reintroducing chat functionality similar to the Miiverse text chat could present new challenges for Nintendo in maintaining a safe gaming ecosystem.

The true purpose of the C button, if it exists, should become clear soon. According to multiple sources, the Nintendo Switch 2 is set for an official announcement this Thursday, January 16.
