The iPhone, Apple's multifunctional smartphone, uses a touch-sensitive interface. Instead of physical buttons, it uses virtual keys that you can tap or swipe to initiate a command. When you tap on an app icon, you open the app, and when you swipe your finger across the home screen, you advance to the next screen of apps. Toggling on the iPhone involves the use of a similar virtual command.

Open "Settings," an app that includes toggle switches in many locations. At the top of the Settings screen is Airplane Mode with an On/Off toggle switch next to it.
Press your finger on the toggle button.
Slide your finger to the right while touching the button. The button slides to the On position and displays a green background. This action activates Airplane Mode.
Touch the toggle button again and slide your finger to the left to the Off position to turn off Airplane Mode. The green background disappears. This is the basic principle for any toggle switch on the iPhone.
