Nintendo Switch 2’s C button activates a suite of social features called GameChat, but requires a Nintendo Switch Online subscription starting in April 2026. Nintendo risks confusion and backlash from players and parents when the C button stops working for everyone without an NSO subscription.

Nintendo has posted a new short teaser video focused entirely on the Switch 2's mysterious C button. This seems to confirm that Nintendo knows that since officially revealing the console in January, we all can’t stop theorizing what the button does. We’re hoping to finally know via the upcoming console’s April 2 showcase.

The C button, used to launch Nintendo's GameChat feature, will essentially be useless to those who do not want to pay for an NSO membership.
