As it turns out, one of the defining upgrades of the Nintendo Switch 2 is actually an old concept developed for the original Nintendo Switch.

However, a video does show off the large button on the back of the new Joy-Cons on the official Nintendo Switch 2 website. Originally discovered and shared on r/NintendoSwitch2, the looping clip reveals that pressing this button down is what disengages either Joy-Con from the handheld.

Perhaps more importantly, the video shows the Joy-Con clicking onto a separate piece before going into mouse mode. This other piece looks like it has some small pads on the bottom, like a computer mouse would, to make it a little easier to slide around.

Now that one rumored Nintendo Switch 2 Joy-Con feature seems to be confirmed, the console just needs a specific companion peripheral to go with it.

The arrival of the Nintendo Switch 2 heralds some much-needed improvements over its predecessor, especially its Joy-Con controllers. Here’s a quick breakdown of what the announcement trailer showed us about the Switch 2’s Joy-Cons.

Similar to the first iteration of Joy-Cons, hitting a dedicated button will detach the controller. It's not entirely clear which mechanical function this button affects, but judging by the design of the Switch 2, the animation suggests that the magnetic charge is switched off.

This new square button, placed at the bottom of the Joy-Con, is unmarked, but prior reports have indicated it’s called the “C” button.
