For many children with physical disabilities, playing with off-the-shelf toys is not possible. Depending on their unique abilities, a toy may not be accessible.
However, if a child can move their foot, head, arm, mouth or any other part of their body, it is possible to add an accessibility switch (or switches) to the toy so that they can play with it. Accessibility switches come in a variety of styles and can be actuated by different body parts and varied motions.
See enablingdevices.com/catalog/capability_switches/best-sellers for some great examples of accessibility switches.
The toy adapted for this instructable is a 2-button remote control train. We will add two switch jacks to the remote control unit so any type of accessibility switch can be swapped in to control the toy. For example, if a child is able to move both their mouth and their left foot, a mouth switch and foot switch could be plugged in so that they could use this train to chase their cat.
Adding switch jacks to this toy will not affect the original quality of use - the existing buttons will operate as normal.
