JoyCable

The JoyCable is a quick and easy way to plug switches into a computer. The JoyCable plugs into the USB port of your computer.  You can connect one or two switches, with standard (3.5mm) switch inputs. No drivers are needed to use the JoyCable with popular software such as The Grid 2, Clicker or Widgit software.

Switch Driver is a free download from Sensory Software that enables you to use your switches for various computer tasks. The link to the download is at the bottom of the page.

If you wish to use the Joycable with a Mac then you might want to consider 'USB Overdrive' (third party software).

To use JoyCable with switch games and other programs that use keyboard keys or mouse clicks as a switch input, we include Switch Driver from Sensory Software. Switch Driver will convert switch presses into other signals, such as a keypress or a mouse click.

Note that you do not need Switch Driver to use The Grid 2 and many other programs that work directly with the JoyCable.
