A switch is a device that enables individuals
with disabilities to control battery operated
or electrical equipment such as toys, appliances
or computers. There are many different types
of switches available from several manufacturers.
The type of switch selected is dependent on
the person's physical capabilities such as using
his/her hands, arms and legs. There are switches
