    The Open Wobble Switch is a cost effective, open source assistive switch similar to commercially available Wobble Switches. The switch is activated by applying force to and moving a wand in any direction. The switch can be activated by various body parts including the limbs and head. It provides a momentary closed contact that can be used to activate various assistive devices.

    The switch provides a momentary closure to a 3.5 mm jack. The switch can be plugged directly into a suitable assistive device and can be used to access a computer or smartphone using a suitable switch interface. The switch can be plugged directly into the Xbox Adaptive Controller.


    This is a very simple switch to assemble and does not require any soldering. A screwdriver and wirestrippers are the only tools required. All of the necessary files and instructions are available at the GitHub repository linked above.


    The switch has a female 1/4-inch-20 thread that is compatible with camera mounting systems and most assistive technology mounting systems to provide convenient mounting options.


    The switch requires approximately 0.55 N (55 gf) and about 24 mm of travel to operate at the end of the wire. This may vary depend on the size and type of topper attached. The Open Wobble Switch has an interchangeable topper that can be swapped for different styles. Custom toppers can also be created.



    This iteration of the Wobble switch comes with a threaded connection on the wire that allows different toppers to be used. Currently, there is a ball-shaped topper, a tee-shaped topper, and a hand-shaped topper. Ultimately the goal is to make the ball and tee shaped toppers fully customizable.

    The original Fusion files are available on Github, but we’ve made it really easy to make a custom topper using TinkerCAD: https://www.tinkercad.com/things/hLjlR0M9PSN-openwobbletopper-flat . This design includes the shapes that make up the socket part that attaches to the topper base. Simply add the shapes you like, align the different portions, combine them all together and export as an stl.

    We’ve made a number of updates to the design and released version 1.1. All the files are available at https://github.com/makersmakingchange/Open-Wobble-Switch


    A number of the switches were built as part of the testing and development. If you would like to try one or test one out for us, please get in touch.
