The Switch 2's Mystery C Button Makes A Weird Sound When Pressed

Another Switch 2 C button tease has arrived courtesy of the Nintendo Today app, on the eve of the big Switch 2 Direct. While we still don't know what the mystery button does, we now know what sound it will make when it's pressed.

In a brief clip shared on Nintendo Today, the C button--a mysterious input that sits below the home button and is simply labelled "C"--is shown to make a cute noise when pressed. The clip is followed by a reminder that the Switch 2 Direct is happening today (in some time zones), when we will presumably find out for sure what the new button does.

The sound in the video is a classic piece of quirky Nintendo sound design, with some comparing it to the distinctive Mii sound effects. The reveal has renewed speculation over the button's function, with the Mii comparison leading some fans to guess that the C could stand for "connect" or "community," and would enable social features for the console.

Another popular guess is that the C button is a capture button, and the sound in the video is Nintendo's take on a screenshot sound effect. Another compelling option is "cursor," tying into ongoing rumors that the Switch 2's Joy-Cons will feature mouse functionality, in which case the C button could be used to change input modes for the Joy-Cons.

The fact that Nintendo gave the button its own teaser only makes the mystery of the C button more intriguing, but it won't be long until we find out definitively what it does during the Switch 2 Direct, happening on Wednesday, April 2 at 6 AM PT / 9 AM ET.
