Playback Switch

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. This device is intended for users of assistive switches who would benefit from or prefer additional audio feedback when using a switch.

A secondary user records a message up to 30 seconds long onto the device by holding the black button on the bottom. The Playback Switch can then be connected to a device just like any other assistive switch. The primary user can then press the button, and it will activate the connected device as well as play back the recorded message.

The Playback Switch is designed for users of assistive switches who would benefit from or want additional audio feedback on button presses.

This project requires the use of a soldering iron, hot glue gun, and a drill.

This build requires opening the commercially available button, gluing in an additional switch, soldering in a cable and reassembling the button.
