This works great allowing you to turn on/off your LED push buttons/joysticks and marquee without turning off your system. Don't forget to purchase an additional 5.5MM X 2.1MM Male DC Plug to JST2 Quick Connection if you want to power on/off 2 items. And get (2) 5.5 X 2.1MM Female DC Power Plug Jack Adapterswhich you can find on the site.
Note: all components shown were purchased at diyretroarcade (sanwa joysticks, push buttons, etc.) Current panel is a prototype, so far all of the components purchased are working without any issues.
This is exactly what I was looking for it worked perfectly......Thank you DIY Retro Arcade......Would have been a five star but the shipping wait time was pretty bad.
