The Playback Switch is an assistive switch that also plays a prerecorded message up to 30 seconds long when the button is pressed. It has a diameter of 90mm and an activation force of roughly 250 grams. The switch is made entirely with commercial, off the shelf parts, with no 3D printing involved. It has a similar functionality to the BIGmack and LITTLEmack buttons. This device is intended for users of assistive switches who would benefit from or prefer additional audio feedback when using a switch.

The device is comprised of off-the-shelf electronics and 3D printed parts. The overall cost of materials is about $8 (plus $8 for component shipping).

The current version of the device (v1.0) has been built and user tested.

This is an open-source assistive technology, so anyone is free to build it. All of the files and instructions required to build the device are contained within this repository. Refer to the Maker Guide below.

You may also submit a build request through the MMC Library Page to have a volunteer maker build the device. As the requestor, you are responsible for reimbursing the maker 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 device for someone who needs it, visit the MMC Maker Wanted section.

The Maker Guide contains all the necessary information to build this device, including tool lists, assembly instructions, and testing.

The Bill of Materials lists all of the parts and components required to build the Playback Switch.

Reference the Assembly Guide section of the Maker Guide for the tools and steps required to build each portion.

As open source assistive technology, you are welcomed and encouraged to improve upon the design.
