The Joy-Con 2 is the linchpin of the Nintendo Switch 2 handheld experience. And nearly a full year after the device’s release, you can finally swap your controllers with a third-party alternative that’s built to outlast the dreaded “stick drift.” The regular ol’ Joy-Con 2 controllers are using sticks that will inevitably break. That’s because the age-old potentiometer joysticks, like those in Nintendo’s consoles, are designed with two physical components that use electrical currents to determine stick orientation. That friction will inevitably wear down the components. Tunneling magnetoresistance, or TMR, instead measures minute differences in magnetic fields. It’s potentially very accurate and more power-efficient than the methods leveraged by traditional sticks. Better still, TMR is built with fewer moving parts that can cause breakage. Gulikit, which makes controllers and other handheld accessories, now sells $20 TMR Joy-Con 2 stick replacements.…
