Turn on Switch Control on Apple TV
To connect a switch to Apple TV, you can connect an external Bluetooth® device such as a keyboard, or you can use the platform-switching feature that forwards switch actions from another device such as an iPhone or a Mac. On an iOS or iPadOS device, tap the screen to trigger the switch. (On iPhone 6s and iPhone 6s Plus or later, press the screen.)
Add a switch and choose its action
In Settings
on Apple TV, go to General > Accessibility > Switch Control > Switches, select Add New Switch, then follow the onscreen instructions.If you add only one switch, it functions as the Selected Item switch by default.
If you’re adding an external switch, you need to connect it to Apple TV before it will appear in the list of available switches. Follow the instructions that came with the switch. If the switch connects using Bluetooth, you need to pair the device with Apple TV. For more information, see Connect Bluetooth devices to Apple TV.
