Switch activation is great for users who can look at targets but prefer to use a physical button to confirm selections, rather than dwelling.

1. First make sure you have a switch already plugged in to your device. Devices like Grid Pad 13 Grid Pad 15 or Tobii I-Series have switch ports on the device. 
2. To set up the Switch Activation, go to Menu > Settings > Access > Eye Gaze or Pointer 
3. Under ‘Activate’, you can select ‘Press switch to click’.
4. select ‘OK’ to save and confirm the setting changes.
