Firstly, apologies as I'm very new to electronics!
I'm converting an old broken Atari 2600 to be an enclosure for my ODroid UX4 single board computer. I thought it would be nice to be able to run the odroid's power wire (5.0V/4A DC) through the Atari's original power switch (https://console5.com/store/atari-2600-slide-switch-power-difficulty-color-new-old-stock-c010373.html) so it actually works as a power switch but not sure if this would be safe- if the switch would handle that kind of power? Can't find any details about the switch or what it is rated for? Is there anyway to test this or are the voltages/ amps so low that it's not a concern?
