Voice4u has become switch accessible and supports the Bluetooth Switch Interface (BSI) from RJ Cooper & Associates. 

Any switch that has a 3.5mm mono plug works with the BSI. Wide varieties of switches are available from many companies, but we would like to show how to make your own switch from scratch here.

  • Push button
  • Wire
  • Solder, soldering iron, cable stripper

Warnings:

  • Create a well ventilated work area where you do soldering. When you heat up solder with a soldering iron, it may make fumes that could be hazardous if they are not properly ventilated.
  • Please do not lay the soldering iron on any flammable surface.
  • Put on safety goggles and work gloves. Wear a long-sleeved shirt is recommended.
  • Don't forget unplugging the soldering iron after you finish working.

Tip

We will make this stuff animal an AAC switch.


  


Here, we are using a snapping switch.




Cut the back of the stuff animal and insert the switch.




We added extra stuffing to make it stiffer and more stable. And stitched it. 





That's it!
