Overview

• Nintendo filed two patent applications on August 7, 2025, with the World Intellectual Property Organization for a crank and a clickable wheel accessory for Joy-Con 2 controllers.
• The crank attachment features a rotary disc tracked by the Joy-Con 2’s optical mouse sensor through a window and is secured by two magnets.
• The clickable wheel uses a gear train to register rotation via the mouse sensor and maps its click action to the SL button with a secondary input for SR.
• Both concepts leverage the Switch 2 Joy-Con 2’s built-in optical-sensor mouse functionality to introduce new tactile gameplay inputs.
• Nintendo has made no announcements about production, and fans are already speculating that the crank could simulate fishing reels in games like Animal Crossing.
