Interesting…I would be REAL CAUTIOUS on one thing:
How are these switches ‘turned off and on’?
There is a thing called ‘switch debounce’ which you most likely have seen before. Where is like when you turn off a light at its switch and you see a spark behind the face plate. This is switch debounce.
It can BLOW UP YOUR COMPUTER! You NEED electronic switches - NOT MECHANICAL ONES!
“…This means that the act of closing the switch will result in a surge current of 5V / 0.2Ω = 25 amps (eeek)…”
You need to either read the specs or contact the manufacture and ask them what type of switches they are using.
All it will take is one time to fry everything you have.
And so you can understand, it takes only .1 amp to kill a human - In the above article, he got 25 amps!
Amps are what kill, not volts. You can equate volts to a person height and amps to how strong they are. A tall person with no muscles is not much of a threat unlike a short person with a lot of muscles…
The Sabrent is NOT listing what they use, you need to inquire.
The wording typically used is SOFT SWITCH. This is what most TV and PC’s use today to turn them off or on.
