Switch access

It may allow users to control a computer, power wheelchair, video game console, tablet, smartphone, toy, and a variety of other electronic devices.

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).

[citation needed] Switches can be suitable for people with cognitive difficulties, developmental delays and physical limitations.

A single switch requires less physical control and is usually less tiring to access but it reduces scanning options and usually leads to a slower rate of input.

These can greatly increase input rates and can make using a computer or electronic assistive device far more comfortable and efficient.
