Dollar Switch

“This video demonstrates how to make a dollar switch. It’s called a dollar switch because it cost about one dollar to manufacture. I can’t loan away several big red switches; however, I can give away many of these ‘dollars’ that function the same way.”
— Jon Turnquist, MOL, OTR/L, ATP, Director, Assistive Technology Services and Lab, Occupational Therapy Department,  St. Ambrose University

Cautions and Warnings

  • Always use safety glasses
  • Use lead free solder
  • Never pass the soldering iron to another person; always place it back in the holder
  • Don't "talk" with your hands when holding the soldering iron
  • ONLY ADAPT BATTERY-POWERED EQUIPMENT (working with line voltage, i.e. 110Volts AC, is extremely dangerous to you and your clients)
