This Switch Pro Controller tester checks Nintendo's Pro Controller on a Windows, Mac, Linux or ChromeOS computer, or an Android phone, with no Switch console. Press any button and the Switch drawing lights up B, A, Y, X, the shoulder buttons, ZL and ZR, Minus, Plus, Home, Capture and both stick clicks. The scopes show where each stick sits and moves, and the tabs measure stick drift, circularity, vibration and the update rate. In Chrome and Edge, Connect for extras reads the battery level and the gyroscope and accelerometer straight from the controller.
How to test a Switch Pro Controller on PC
- Pair it: hold the small sync button on top of the controller, next to the USB-C port, until the player lights run back and forth. Add it in your computer's Bluetooth settings as Pro Controller. Or connect it with a USB-C data cable.
- Press any button. The page switches to the Switch drawing.
- Press every button and both sticks down. Each one turns green once it works.
- Press ZL and ZR. They are digital on the Pro Controller, so their bars jump straight from 0 to 100 percent.
- Run the Stick drift test and the Vibration motor check.
- In Chrome or Edge, press Connect for extras to see the battery and motion sensors.
What the results mean
| Readout | Normal result | Look into it when |
|---|---|---|
| Buttons tested | All face, shoulder and system buttons | One never turns green |
| Stick distance at rest | 0.00 to 0.05 | Above 0.10 with your hands off |
| ZL and ZR | Jump from 0% to 100% | They flicker while held |
| Circularity | A round outline | An orange dent toward one direction |
| Battery | Full, Medium, Low or Critical | Low right after a full charge |
| Reports per second | Steady, often 60 to 125, from the controller itself | Much lower near other wireless devices |
The Pro Controller reports its battery in rough steps, not in percent, so the extras panel shows Full, Medium, Low, Critical or Empty.
A and B are swapped in games
On this page the buttons are named by position: the bottom button is B and the right one is A, exactly as printed on the controller. PC games built for Xbox controllers expect A at the bottom, so they read your B button as A. In Steam, the controller settings have a Nintendo button layout option that swaps them back. If the swap happens here too, the controller is in a mode or a third party copy that reports Xbox positions.
A stick drifts or will not center
Put the controller on a table and run the drift test. A resting offset under 0.05 is normal. If it is higher, calibrate the stick on a Switch first: System Settings > Controllers and Sensors > Calibrate Control Sticks. Calibration is stored in the controller, so run the test again on the PC afterwards. If the offset returns, the stick is worn. The stick drift tester explains deadzones and the how to fix stick drift switch guide covers cleaning and stick replacement.
The Pro Controller will not pair with a PC
- Charge it for 30 minutes first. A flat Pro Controller shows no lights.
- Hold the sync button until the lights run, then add it in Bluetooth settings within about 30 seconds.
- If it pairs but this page sees nothing, press a button: browsers hide controllers until then.
- A nearby Switch can grab the controller again when it wakes. Put the Switch in airplane mode or move away from it while testing.
The controller not connecting to pc guide has the Windows driver steps.
Motion sensors and battery
Connect the extras, lay the controller flat and press Zero at rest. Tilting it moves the green bubble, and turning it shows the gyro in degrees per second. A gyro that keeps reading tens of degrees per second while the controller lies still causes aim drift in motion controlled games. Recalibrate it on a Switch under System Settings > Controllers and Sensors > Calibrate Motion Controls. The joycon tester pc does the same for Joy-Con, and the controller latency tester compares cable and Bluetooth timing.
What this Switch Pro Controller test cannot check
- The NFC reader used for amiibo. Only a Switch can read it.
- HD rumble detail. Browsers send simple rumble, so the gamepad vibration test confirms the motors but not every texture.
- Pairing with the Switch. A controller that works on PC but not on the console needs re-syncing in the Switch's Controllers menu.
Switch Pro Controller tester questions
Can I test a Switch Pro Controller on PC?
Yes. Pair it by holding the sync button on top until the lights run, add it in your Bluetooth settings, or connect a USB-C data cable. Then open this page and press any button. No Switch console is needed.
Why are A and B swapped in my PC games?
Nintendo puts A on the right and B on the bottom, the opposite of Xbox. This page follows the button positions, so the bottom button shows as B. In Steam, turn on the Nintendo button layout option in the controller settings to match the labels in games.
How do I calibrate a Switch Pro Controller?
On a Switch, open System Settings, then Controllers and Sensors (Controllers & Accessories on a Switch 2), then Calibrate Control Sticks, and follow the steps. On a PC there is no Nintendo calibration, so use a deadzone in the game or in Steam if a stick drifts.
Can I test a Switch 2 Pro Controller?
If your computer recognizes it, yes: connect it, press a button and the page tests every input your browser receives. Support for newer Nintendo controllers depends on your system. If it never appears, test it on the Switch 2 under System Settings, Controllers & Accessories, Test Input Devices.
Does the vibration test work with HD rumble?
Partly. Browsers send classic two motor rumble, which the Pro Controller plays through its HD rumble motors as a simple buzz. That is enough to confirm both sides vibrate, but not to test the fine textures games use.
