    A wobble switch is a switch that can be activated by moving a ball or rod in any direction The switch typically has a fairly low activation force and can be activated with various parts of the body including: hands, head, chin, tongue through cheek. The springiness means they can be useful for users who are able to perform gross motor movements.

    A number of commercial wobble switches are available, but they are quite expensive.

    **Commercially Available Wobble Switches**

    A cost-effective alternative has been specifically requested by a children’s rehab program.

    The purpose of this thread is to assess how much interest there is in this design, and what sort of features are important.

    * An open source wobble switch design would be useful for me or someone I know.
    * I would like to test prototypes and provide feedback.

    Please comment below:
    1. Any important features this design should have
    2. Any existing open source projects


    We’ve started some initial design work on an open-source Wobble Switch, and have a functional prototype:


    The design currently uses a commercially available limit switch (e.g., $18 for 3), some fasteners, and some 3D printed components. This design is a work in progress, but preliminary files are available on GitHub:

    Over the next while, we will be looking at a more modular design for the wand topper and developing a full set of documentation. If you have any ideas or want to get involved in the design and/or testing, let us know.


    I’m not here for posting spoilers, but are you going to let people know it’s public now?

    :raised_hand_with_fingers_splayed:t2: on the high-five option!


    An initial version of this switch has been released to the MMC Library here:

    The design could benefit from some more testing, so you can submit a request through the site or add a message to that topic.
