switch

37
Q

a variety of switches which allow people with limited movement to access devices with the slightest movement of a finger or wrist.

A

light switches

39
Q

allow people with movement limitations to use their voice or any distinct sound to operate the switch. simply saying “ahhh” can make the switch perform a desired action.

A

sound switches

40
Q

usually have a soft foam that serves as the activation surface. when the soft surface is pressed, it gives tactile feedback and an audible click. may be activated by the head, shoulders, arms, or hands.

Q

large button switches that are suitable for people who can’t use the small buttons and controls on most adapted devices. usually have a very large button that is ergonomically designed to respond to the gentlest touch.

A

plate switches

42
Q

ability switches that are specially designed for those who are unable to control or sustain the hand or wrist movements necessary to activate traditional plate switches. activated with just a light touch and some can be angled to accommodate varying abilities.

A

saucer switche
