Switch access
Switch access is the use of one or more switches to operate computers and other devices and is primarily used by people with severe physical or cognitive impairment.[1] A switch is an assistive technology device that replaces the need to use a computer keyboard or a mouse. It may allow users to control a computer, power wheelchair, video game console, tablet, smartphone, toy, and a variety of other electronic devices.
Types of switch
Switches come in a variety of shapes and sizes depending on the action used to activate them (such as sip-puff, pushing, pulling, pressing, blinking or squeezing). Switches also vary in their colour and aesthetics. For push or press switches, the amount of force required to operate them varies or in some cases can be adjusted. Some switches may only require a touch (not even a press), some may be designed to be kicked.

What can be accomplished with a switch
Switches can be suitable for people with cognitive difficulties, developmental delays and physical limitations. In the simplest use they are a clear and simple way to demonstrate action/reaction often referred to as cause and effect. In the more complex use, they could be the means to control mobility or interact with the environment. There are a variety of motivating switch activities that can be used to assess and develop a person's understanding of choice and timing.
