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.
In the video, the trigger is pressed down a tad before a final push releases it from the console. As the Joy-Con moves away, you can also see a small cylinder receding back into the top part of the inside of the controller; to me, that indicates that when you push the trigger, you’re actually pushing out that cylinder to help bump the Joy-Con out.
Here’s a GIF of the relevant part of the video:

The mechanism to remove the Joy-Con controllers looks similar to what was included in a 3D-printed mockup that accessories-maker Genki brought to CES.
However, as for how the controllers actually stay attached to the Switch 2, Nintendo so far hasn’t said if the console uses magnets, as has been rumored. It’s one of many unanswered questions — hopefully, all will be revealed at Nintendo’s Switch 2-focused Direct on April 2nd.
