Turn on Switch Control on Apple TV 4K
To connect a switch to Apple TV 4K, 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 iPhone or iPad, tap the screen to trigger the switch. (On iPhone 6s and iPhone 6s Plus or later, force-click the screen.)
Add a switch and choose its action
Go to Settings
on Apple TV 4K.Go to Accessibility > Switch Control > Switches.
Select Add New Switch, then follow the onscreen instructions.
If you add only one switch, it functions as the Select Item switch by default.
If you’re adding an external switch, you need to connect it to Apple TV 4K 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 4K. For more information, see Connect Bluetooth devices to Apple TV 4K.
Turn Switch Control on or off
Go to Settings
on Apple TV 4K.Go to Accessibility > Switch Control, then select Switch Control to turn it on or off.
Tip: You can also set up an accessibility shortcut to activate Switch Control.
