iPhone These techniques work whether you’re scanning by item or by point.
Select an item. While the item is highlighted, trigger the switch you’ve set up as your Select Item switch. If you are using a single switch, it is your Select Item switch by default.
Display available actions. Select an item using the Select Item switch. Available actions appear in the control menu that appears.
Tap an item. Use your selection method to choose Tap from the control menu that appears when you select the item. Or turn on Settings > General > Accessibility > Switch Control > Auto Tap, then just select an item and do nothing for the Auto Tap interval (0.75 seconds if you haven’t adjusted it). Or set up a switch specifically to perform the tap gesture at Settings > General > Accessibility > Switch Control > Switches.
Perform other gestures or actions. Select the gesture or action from the control menu that appears when you select the item. If you have Auto Tap turned on, trigger your switch within the Auto Tap interval, then select the gesture. If there is more than one page of actions available, tap the dots at the bottom of the menu to go to another page.
Dismiss the control menu. Tap while all the icons in the menu are dimmed.
Scroll the screen to see more items. Select any item on the screen, then choose Scroll from the control menu.
