Navigate iPhone Using External Switches
Switch Control lets people operate iPhone using one or more adaptive switches, the screen, or a camera instead of direct touch, scanning through items on screen until the desired one is selected.
How to open Switch Control
- Open Settings → Accessibility → Switch Control
- Tap Switches to add and configure input sources
- Choose a scanning style (Auto, Manual, or Step)
- Adjust timing under Auto Scanning Time and Tap Behavior
- Toggle Switch Control on to begin scanning navigation
What you should know
- Supports auto scanning, manual scanning, and single-switch step scanning modes
- Works with external Bluetooth switches, screen taps, or head/camera tracking as switches
- Recipes let you assign custom actions to switch combinations
- Point Scanning narrows selection with crosshairs for precise taps
- Adjustable scanning speed, auto-tap timing, and highlight color
Why it matters
Switch Control is often the only practical way for people with limited mobility to operate a touchscreen device independently. By turning nearly any binary input—a single button, a sip-and-puff device, or even a head movement—into full iPhone navigation, it opens up communication, entertainment, and productivity apps that would otherwise be inaccessible. Because it works system-wide rather than per-app, it removes the need for specialized hardware or software beyond the switch itself. Getting scanning speed and recipes tuned correctly can dramatically change how efficiently someone can use their device day to day.
Best practices
- Start with a slower scanning speed and increase it as the user gains familiarity
- Use Point Scanning for apps with small or closely spaced controls
- Create custom recipes for frequently repeated multi-step actions
- Pair a physical switch via Bluetooth for more reliable, lower-latency input than screen taps
Common problems and fixes
- Scanning feels too slow or too fast for the user
- Adjust Auto Scanning Time and Tap Behavior individually in Switch Control settings
- A Bluetooth switch isn't recognized
- Re-pair the switch in Settings > Bluetooth, then add it again under Switch Control > Switches
- Scanning skips over needed on-screen elements
- Switch to Item Mode with a different scanning style, or enable Group Scanning
Tips and tricks
- Use the Switch Control recipe editor to build shortcuts for common multi-tap actions like copy-paste
- Enable auditory or visual scan cues to make timing predictable for new users
Frequently asked questions
Can I use my iPhone's screen as a switch?
Yes, Full Screen can be set as a switch so any tap on the display advances the scan.
Does Switch Control work with third-party apps?
Yes, because it operates at the system accessibility layer, it works with most apps that use standard iOS controls.
Can I combine Switch Control with Voice Control?
They can both be enabled, but only one is typically the primary input method at a time to avoid conflicts.

- Language & RegionLanguage & Region controls which language iOS displays system-wide, plus region-specific formatting for calendars, number separators, measurement units, and temperature — separate settings that don't have to match each other.
- VoiceOverVoiceOver is iOS's gesture-based screen reader that describes aloud everything on screen — text, buttons, images — letting blind and low-vision users navigate the entire iPhone by touch and sound instead of sight.
- MagnifierMagnifier uses the iPhone's camera to magnify nearby text, objects, or your surroundings in real time, with added tools like Detection Mode for identifying people, doors, and objects for users with low vision.
- Sound RecognitionSound Recognition uses on-device listening to identify sounds like alarms, doorbells, sirens, car horns, or a crying baby, and sends a notification when one is detected nearby.
- Guided AccessGuided Access temporarily restricts iPhone to one app and lets you disable specific screen areas, hardware buttons, or gestures, helping someone stay focused or preventing accidental exits.
- Captions & SubtitlesCaptions & Subtitles controls whether closed captions appear by default during video playback and lets you customize their font, size, color, opacity, and background style.
