Switch-activated devices can be used by students in many academic and recreational ways.

In order to provide switch access to appliances/toys, the following is necessary:

  • battery or electrical power source
  • switch connection

If the appliance/toy is battery-powered, a small device, called a battery adapter or interrupter, can be inserted between the connection points in the battery compartment. A switch (e.g. Big Red, leaf, JellyBean, string, toggle, etc.) can then be connected to this battery adapter. When the switch is activated, the appliance/toy will come on! (Note: leave the appliance/toy in ON position while the switch is being used). A battery control unit can also be added to this configuration to provide greater control in how the device is activated.

If the appliance/toy is electrically-powered (plug-in), then a power control unit (e.g. PowerLink III) must be used to provide the switch interface. Depending upon the complexity of the power control unit, a varied number of switches, devices and control modes will be available. The power control unit is plugged into the electrical plug-in on the wall; the appliance/toy is plugged into the socket on the power control unit; and the switch (e.g. Big Red, leaf, JellyBean, string, toggle, etc.) is plugged into the switch-jack on the power control unit. When the switch is activated, the appliance/toy will come on! (Note: leave the appliance/toy in ON position while the switch is being used). Please use caution when using any electrical equipment with children and be sure to disconnect power sources when not in use.
