Switches are very simple devices which can be used flexibly with a variety of children and adults.
The most commonly used switches are simple press and release switches. It is possible to use a switch to operate hardware such as toys and tape recorders. This also give different modes of operation - e.g. turned on for a set time. There are many software programs that use switches. Most of these programs involve a visual-building exercise followed by a 'reward' sequence.
