​Switch Access with Power Select

APH Power Select
The APH Power Select (or similar switch interface devices) allows students to operate standard electrical appliances using an adaptive switch. This is especially helpful for students with physical, visual, or multiple impairments.
When using Power Select:
  • Choose electronic items with a simple on/off toggle switch (not a button that resets each time), as these are required for proper switch functionality.
  • For students with residual vision, prioritize devices that offer steady, switch-activated lights. Avoid flashing or strobing lights, which may pose a seizure risk.
  • Switch access benefits students with all levels of vision, supporting independence, exploration, and engagement across activities.
Suggested Switch-Accessible Activities:
  • Vision Activities: Desk or clip-on lamps highlighting visually interesting materials, fiber optic lights, or seasonal decorative lights
  • Vocational Activities: Electric stapler, paper shredder, small vacuum cleaner, etc.
  • Leisure Activities: Box fan to move or blow lightweight materials, radio, CD player, or other audio devices
  • Cooking Activities: Blender, electric ice crusher, juicer, electric kettle, waffle maker, food processor, hot air popcorn popper, etc.
These tools allow students to participate more actively in daily routines, work tasks, and play, building confidence, independence, and skill through accessible technology.

​Switch Access with Battery Interrupter 

​Don’t limit switch-accessible items to those with a power cord; battery-operated devices can also be adapted using a battery interrupter. A battery interrupter is a simple tool that allows a switch to control a battery-powered device. To use it:
  1. Insert the interrupter between the battery and the battery contact in the compartment (usually at the end of one battery).
  2. Plug the interrupter's cord into a switch, such as the APH Select Switch.
  3. When the switch is activated, it redirects the flow of electricity through the interrupter, turning the device on or off.
As long as the device has a mechanical on/off switch (not a touch or reset button), it can typically be made switch-accessible using this method!

​Switch Interface & Switch

A switch interface paired with a switch enables students with visual, physical, or multiple disabilities to access computer-based cause-and-effect activities, supporting learning and engagement.
How it works:
  • Plug the switch interface into a USB port on any computer.
  • Connect a switch to the interface.
  • When the switch is activated, it triggers an action on the screen, ideal for cause-and-effect learning.
Features:
  • Compatible with most computers.
  • Available in a range of models and prices.
  • Works with a variety of free and paid software designed for switch access.
Suggested websites for switch-accessible activities:You can also create custom cause-and-effect games using PowerPoint. With simple animations and timed transitions, interactive slides can be controlled with a switch to match student goals and interests.

​Recordable Switches for Sensory Choice

Recordable switches, such as the Big Mack, can support communication and choice-making during sensory activities.
Example Activity:
  • Program the switch to say “More, please.”
  • Offer the student a preferred sensory experience, such as:
    • Smelling essential oils
    • Receiving a hand massage
    • Enjoying a tickle or light touch
  • After briefly providing the activity, pause and prompt the student to activate the switch to request more.
This approach encourages:
  • Cause-and-effect understanding
  • Intentional communication
  • Active participation in enjoyable routines
Over time, students learn to associate the switch activation with getting something they enjoy, supporting early language development, and autonomy. 

​Computer with Touch Screen

Touch screen computers are valuable tools for engaging students in interactive learning while supporting multiple skill areas.
Benefits:
  • Cause-and-effect learning: Students can see immediate outcomes of their actions, reinforcing purposeful interaction.
  • Visual efficiency skills: Visual attention, visual scanning, visual tracking, visual discrimination
  • Eye-hand coordination: Direct interaction on the screen promotes precise targeting and movement.
  • Posture support: Using a computer in an upright position encourages improved head and trunk alignment, supporting overall physical development.
Touch screen activities can be tailored to a student’s visual, motor, and cognitive needs, making this technology highly adaptable and motivating.

​Tablets

Tablets with touchscreens are excellent tools for students with complex needs due to their portability, customizable positioning, and visual appeal.
Benefits:
  • Can be positioned within the student’s visual field for optimal access.
  • Offer a wide variety of cause-and-effect apps that promote: visual attention, visual scanning, and eye-hand coordination
  • Backlit screens make them ideal for students who are visually drawn to light.
Tip: Use the Guided Access feature to:
  • Lock the student into a specific app
  • Disable certain areas of the screen
  • Block ads and external links
  • Prevent changes to device settings
