A video on Nintendo’s Switch 2 website shows how the trigger (or is it a button?) on the back of the Joy-Con controllers disconnects them from the console, as spotted by Polygon.

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.

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.

Nintendo’s short video offers a closer look at the Switch 2 Joy-Con, showcasing how the controller works and attaches to the console.

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.

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.

The Switch's producer was "particularly excited" about the idea at the time, but it didn't work well enough back then
