Rocket Switch Interface

The Rocket Switch Interface enables users to operate their computer or smartphone using up to two assistive switches. This compact switch interface is connected to your device using a USB to USB-C adapter (or whichever connector style your device has).

There are several ways of using this switch interface. A short, 1-second press will perform the action you assigned in your computer or phone setting.

To change the operation mode, press switch 1 (left) and hold for 4 seconds to cycle through each mode.

• Switch Mode (teal light indicator): This mode can be used with a switch control software on Windows and Android. Switch 1 outputs the A key and switch 2 outputs the B key.
• Switch Mac Mode (pink light indicator): This mode can be used with a switch control software on Mac Operating Systems. Switch 1 outputs the F1 key and Switch 2 outputs the F2 key.
• Mouse Mode (purple light indicator): This mode simulates a mouse button click. Switch 1 performs the left mouse click and Switch 2 performs the right mouse click.

Settings Mode (orange light indicator): The settings mode allows the user to adjust the reaction time between switch presses. The minimum reaction time is 50 ms (Level 10) and maximum reaction time is 500 ms (Level 1). Switch 1 decreases one reaction level and Switch 2 increases one reaction level.

See the User Guide for details.

Switch users with movement-limiting disabilities like spinal cord injuries, muscular dystrophy, and ALS may find this switch interface useful.

This is an intermediate level build that involves 3D printing, soldering small electronics, and software.

This device consists of two 3D printed parts and assembly. Refer to the Assembly Guide for build instructions.
