Switch 2 Joy-Con Tester
The Switch 2's Joy-Con controllers attach magnetically and add new features, including a mouse mode. Like any controller they can develop faults: sticks that drift, buttons that stick or connection problems.
This tester checks Switch 2 Joy-Con in your browser, one at a time or as a pair, so you can confirm they work before buying second-hand or find which part is failing.

What's different about Switch 2 Joy-Con
Switch 2 Joy-Con attach to the console magnetically instead of sliding onto rails, and each can work as a mouse by gliding it across a surface. They're larger than the originals, with bigger buttons.
They aren't interchangeable with original Switch Joy-Con, so if you're buying replacements, check which console they're for.
What to test on Switch 2 Joy-Con
Switch 2 Joy-Con have more to check than many controllers: buttons, sticks, triggers, the motion sensors and the mouse sensor. The table lists each and what this page or the console can test.
Browser support for Switch 2 Joy-Con is limited and may vary by device and browser. If something doesn't appear here, use the console's own controller test as well.
| Feature | What to check |
|---|---|
| Buttons | Every button registers once per press |
| Sticks | Centred at rest, full range in every direction |
| Triggers and shoulder buttons | Register fully |
| Motion sensors | Respond smoothly to tilting |
| Mouse sensor | Tracks smoothly on a flat surface |
| Attachment | Snaps securely to the console |
Testing on the console
Switch 2 has controller settings that include checking input devices and calibrating sticks. Use them alongside this page for a full picture, especially for features a browser can't read.
If sticks show drift on the console, try calibration there first. If drift remains after calibrating, the stick may need repair.
Checking the mouse function
Glide each Joy-Con on a flat surface with the sensor facing down. The pointer should move smoothly without jumping. Shiny, glass or very dark surfaces can confuse the sensor, so test on a mouse mat or plain desk.
If tracking is jumpy, clean the sensor gently with a soft dry cloth.
Magnetic attachment
Switch 2 Joy-Con attach to the console magnetically and are released with a button. Check they click firmly into place and release cleanly. A Joy-Con that comes loose too easily may have a damaged connector.
Keep the magnetic connectors clean. Dust or small metal particles can stop them attaching properly.
Original Joy-Con versus Switch 2 Joy-Con
Original Joy-Con and Switch 2 Joy-Con aren't interchangeable for attaching to consoles. Original Joy-Con can't attach to Switch 2, and Switch 2 Joy-Con can't attach to the original Switch. When buying replacements, check which console they're for.
This page focuses on Switch 2 Joy-Con. Original Joy-Con can be tested on our main gamepad tester.
Stick drift on Joy-Con
Drift was a well-known problem on original Joy-Con. It's too early to say how Switch 2 Joy-Con will hold up over years of use, so testing regularly is a good habit.
If drift appears within the warranty, contact Nintendo. Our Controller Warranty Checker can help you check your coverage.
Connecting to a PC
Support for Switch 2 Joy-Con on PCs is limited and depends on your system and browser. They may pair over Bluetooth but not report every input. As support improves, more features may become testable here.
If your Joy-Con don't appear, test them on the console instead.
The C button
The right Switch 2 Joy-Con has a C button used for GameChat. Press it during the test to check it registers. If the browser doesn't show it, check it works in the console's settings.
Caring for your Joy-Con
Store Joy-Con attached to the console or in a case to keep dust out of the sticks. Avoid using them in very dusty places, and keep drinks away.
Charge them regularly. Lithium batteries last longer when not left completely flat for long periods.
Buying used Switch 2 Joy-Con
Test every button, both sticks, the triggers, the motion sensors and the mouse function before buying. Check they attach securely and charge properly.
Ask for proof of purchase if they're still under warranty.
Joy-Con grip and controller mode
Switch 2 Joy-Con can be used attached to a grip, held separately, or turned sideways as individual controllers. Each mode uses different buttons. Test in the mode you play most.
Checking HD rumble
Switch 2 Joy-Con have advanced rumble that can produce detailed sensations. A browser can't test all of it, so use a game or the console's settings to check it works. A Joy-Con with no rumble or a rattling sound may need repair.
Battery life
Joy-Con charge when attached to the console or a charging grip. If a Joy-Con runs out of battery quickly, the battery may be wearing. Check its level in the console's controller settings.
Pairing problems
If a Joy-Con won't pair, attach it to the console to pair it automatically. If it still won't connect, restart the console and update its software.
Reporting faults to Nintendo
If a Joy-Con has a fault under warranty, contact Nintendo support. Describe the problem clearly and include any test results. Nintendo may repair or replace the Joy-Con.
Testing stick range
Push each stick fully in every direction and rotate it slowly around its edge. The reading should reach the edge evenly in all directions. A flat spot can mean dirt around the stick or wear.
Our Circularity Test shows the stick's full range in more detail.
Testing motion controls
Hold each Joy-Con and tilt it slowly forwards, backwards and side to side. The motion readings should respond smoothly and settle when you stop. If they keep moving while the Joy-Con is still, calibrate the motion controls in the console's settings.
Cleaning Joy-Con
Wipe Joy-Con with a soft, slightly damp cloth. Use compressed air around the sticks and buttons to remove dust. Never spray liquid directly onto the Joy-Con.
Keep the magnetic connectors and the mouse sensor clean for reliable attachment and tracking.
When to replace Joy-Con
Replace a Joy-Con if a fault continues after calibration and cleaning, and the warranty has ended. Check repair options too, as some faults can be fixed more cheaply than buying a new pair.
Buying replacement Joy-Con
When buying replacements, make sure they're Switch 2 Joy-Con, not original Joy-Con, if you want them to attach to your Switch 2. Official Joy-Con are sold in pairs and sometimes separately. Third-party controllers designed for Switch 2 are also available, but check which features they support, such as the mouse function, motion controls and rumble.
Test any new Joy-Con here and on the console when they arrive.
Common problems
Hold the sync button until the lights flash, and remove any old pairing from your computer first.
Pair the second one separately; each connects on its own.
