    Overview

    The Open Rocker Switch is an inexpensive 3D printable accessibility switch. The switch consists of two separate switches that are activated by pressing on either side. The switch is 167 mm L x 79 mm W x 16 mm H and uses a standard stereo 3.5 mm cable. Using the model of tactile switch specified, the activation force is about 1.3 N (130 gf) for each side. This switch is comparable in size, activation force, and travel to the discontinued AbleNet Rocker Switch.

    Usage

    The Open Rocker Switch has a 3.5 mm stereo switch to carry the two signals. It can be plugged directly into AT interfaces that accept stereo connections, or can be used with an adapter to connect to two separate 3.5 mm mono connections.

    Some thoughts from @MMC_Jake on what changes might be necessary to make this design more use-able and make-able long term:
    * It is a long print, and requires a lot of support for the top section.
    * The clearances need to be optimized to fit a wider range of printers.
    * The foam tape pivot is not only tricky to source, but its also tricky to assemble, and mistakes will prevent the switch from working properly
    * The lack of strain relief on the original was a common source of failure
