Switch Mounting Base with Double Clip - SI-06

For (With Whom)

People with motor impairment of the limbs who operate information and communication terminals and similar devices using a push-type switch.

Why

People with motor impairment of the limbs often press a push-type switch using a body part that is easy to move, such as the back of the hand, a foot, or the head. A challenge in that case is how to fix the switch in place. A mounting device that is easy to set up and adjust is therefore useful.

How

Because we needed something that makes the switch easy to set up, easy to reposition, able to hold it in space, and inexpensive to make, we created an attachment for the "Dochira-mo Clip" (double clip), which is commonly used for fixing switches. By removing one of the clips of the double clip, a flexible arm can be used.

Outcome

People with cervical spinal cord injury and people with amyotrophic lateral sclerosis became able to operate a call and change TV channels stably using head movement. In addition, being easy to set up and adjust helped reduce the burden on caregivers.
