The Finger Lift Switch is an assistive switch that is activated by lifting a resting finger upwards. The switch activation distance is approximately 5 mm and the required force is about 5 grams-force.
Connect the cable to an assistive device with a 3.5 mm input jack. The user's lifting fingertip should be placed under the finger lift pad, resting on a lower surface or splint. When the user raises their lifting finger, the finger lift lever will rotate and activate the switch. The switch will de-activate when the user lowers their lifting finger back to the resting surface.
This is an open-source assistive technology, so anyone is free to build it. All of the files and instructions required to build the Finger Lift Switch are contained within this repository. Refer to the Maker Checklist below.
If you would like to obtain a Finger Lift Switch , you may submit a build request through the MMC Library Page. The requestor is responsible for the cost of materials and any shipping.
If you have the skills and equipment to build this device, and would like to donate your time to create the switch for someone who needs it, visit the MMC Maker Wanted section.
Refer to the Maker's Checklist for an outline of the steps required to build the device.
The Bill of Materials lists all of the parts and components required to build the device. The electronic and hardware component needs to be ordered online.
All of the files and individual print files can be in the /Build_Files/3D_Printing_Files folder.
Reference the Assembly Guide for the tools and steps required to build each portion.
