Scroll down and tap Switch Control. This will be under the “Interaction” tab. On the Switch Control menu, you will see several options under “Timing”. Auto Scanning Time: This menu allows you to adjust Switch Control's scanning intervals. Pause on First Item: This gives you the option to set the Switch Control's scanning to pause on the first item in a group. Loops: This allows you to set how many times Switch Control cycles through the screen.
