Two Ginful Switch Pro Controller analog stick TMR sensors. #Note Switch Parts (See various Switch peripheral parts.) Compatible models: All genuine Pro Controllers *Includes low melting point solder, 3mm diameter, approximately 5cm long. Please understand that Hall effect sensors and TMR sensors are different. In terms of performance: Gulkit TMR → (performance is almost the same as Hallpi) Hallpi → Ginful, K-silver, and below that are Hall effect. Compared to Hall effect, they offer higher precision, lower noise, and longer lifespan. Currently, most analog sticks use an analog method, which causes drift due to friction wear. These Hall effect sticks use a digital method, so the parts do not contact each other, making drift due to wear less likely. To calibrate on the Switch console: Select "Settings" (gear icon) on the Switch HOME menu. Select "Controllers and Sensors" → "Calibrate Control Sticks" and follow the instructions until complete.
