Describes a modification to existing large-button switches used to teach cause and effect to children with multiple physical and cognitive disabilities. Students press a large button to activate an item of interest. The device was modified to increase battery life, decrease set up time, and prevent student tampering with the controls. The three cordless switches in the Transmitting System were rewired to operate off of one 9.5 volt rechargeable battery. The Transmitting System was encased in a polycarbonate enclosure with a lighted power switch. The Power and Receiving System contains two PowerLink units and receivers for the cordless switches. The receivers were converted to AC power. A single powerstrip is used for both the PowerLink units and an AC/DC converter. The conversion increased the range of the cordless devices to 20 feet. Set up time was reduced to five minutes. The total cost for this device and its modifications is approximately $900.
