Joyswitcher (Joystick Switcher or Joystick Swapper) for Commodore C64 machines, both breadbin and C64C. Like the C8D version, it can change with the pressed button the JOY1 to JOY2, and of course JOY2 to JOY1 if pushed again.
The panel assembled with Atmel AVR microcontroller and high quality led backlit OMRON tactile button (led color: amber/yellow), and other quality parts. It has a brass hexagon standoff underneath to prevent bending from pressing the switch if attached to your machine’s joyports. Joyswitcher is compatible with all types of joysticks, pens, mice… (and works in SX64 machines too!)
Elmar Wenners tested well, the Joyswitcher working great with Commodore SX64 machines!
Here is a demonstration video from my another happy customer, Adrian Smith:
