5. Connecting a PS4 Controller to Other Gaming Consoles
It's possible to use your PS4 controller with other gaming systems such as the Nintendo Switch and Xbox One. But make sure to unplug your PlayStation 4 console before syncing your DualShock 4 controller with another system to avoid interference from the adapter.

How to Connect PS4 Controller to a Nintendo Switch
To connect a PS4 controller to a Nintendo Switch, you'll need a USB C-to-A adapter. We recommend using the Magic-NS adapter, which is available for purchase on Amazon.

Make sure your Nintendo Switch is powered on, and placed into the dock.
Insert your USB C-to-A adapter into one of the Nintendo Switch's USB ports.
First, connect your Joy-Con controllers to your Switch, then go to the "Home" screen and select "System Settings."
Choose "Controllers and Sensors," and then turn on "Pro Controller Wired Communication." Click "OK" when prompted.
To connect your PS4 controller, plug it into the USB C-to-A adapter with a USB cable. Once it's connected, the LED light on the controller should turn on, indicating that it's been detected.
To connect your DualShock 4 controller to the adapter, first press and hold the button on the adapter until the light on the back starts flashing. Then, simultaneously press the PlayStation button and the Share button on your controller. The adapter should automatically detect your controller.
To use your PS4 controller wirelessly, disconnect it from the adapter.
How to Connect PS4 Controller to an Xbox One
Although the Xbox console is not intended to work with a Sony controller natively, you can use various adapters to make the PlayStation 4 controller work with the Xbox One. This is done with the CronusMAX PLUS adapter.

Connect your CronusMAX PLUS to your PC using an internet connection, and the drivers will install automatically.
Once installed, open the Cronus PRO application and go to Tools > Options > Device.
From the drop-down list, select “Xbox One” as the output protocol labeled "XB1.”
Ensure that the "Enable Dualshock 4/Wiimote Bluetooth searching" box is checked.
Remove the CronusMAX PLUS from your PC and plug it into your Xbox One console using the USB port. The CronusMAX PLUS will display "AU" on its LED screen to indicate that it's authenticating.
Take out the batteries from your Xbox One controller. If any Xbox One controllers are connected to the console, their signal can interfere with the PS4 controller.
Wait until a number appears on the CronusMAX PLUS, then disconnect the Xbox One controller and look for the standby animation. This will look like two halves of a circle spinning around the display.
Connect your Xbox One controller to the CronusMAX PLUS using a USB cable. The adapter's LED display should switch from "AU" to "0."
Connect a Bluetooth 4.0 USB adapter to the CronusMAX PLUS.
Press and hold the Share and PlayStation buttons on your PS4 controller. The controller's light will start flashing white to indicate it's searching for a connection. After a few seconds, the light should change to a solid color, and you're ready to play!
