    Rocket Switch Interface

    MMC Library Link:


    The Rocket Switch Interface is a switch interface device which enables users to operate their computer or smartphone devices using assistive switches. The Rocket Switch Interface supports up to two 3.5 mm assistive switches.

    I’m looking for someone to make me a few of these switch interfaces for some of my students.

    I just want to check that these will fit into a USB port on the computer and the switch actions that will be used will be for “space” and ” enter” .

    If so, I could use at least 5 (or more) of these if someone is keen to make them.





    Hi Cindy,

    You should be able to use USB of computer if it’s USB Type A, you may need an extension cable depending on the model. You can find one in local dollar store if it disconnects easily.

    The software outputs “A” and “B” keys , but you can easily change it to “space” and ” enter”  by changing line 114 and 115 to do it. I can make the changes for you if you need help.


    Hi @cindy , Can you please make the request through our website at ?


    Sorry, did I do that wrong?

    Will try through that link.


    The requests are done through the website in order to match a maker locally to assemble the units.

    The Forum is used to share and collaborate in projects, get feedback about projects  or turn ideas to devices.

    No worries, we will be able to help once the request is received.
