Anybody know what the forward amps output for the main switch is on the petit crouton?
If you are talking about the output from the 3.3V pad, it is 20 mA. Other than that, I have no idea what you are asking about.Quote:

It's less than 50mA for sure. I've seen people wire up their boards incorrectly and hook 20ma accent LEDs to the switch points. The accent LEDs lit up a bit dim, but didn't blow, so I'm assuming it's less than 20mA.
Just to clarify, according to the PC manual the accent pads put out 3.3V at 18mA.
The accent pads do that, the main 3.3V (which is what I was talking about) can put out a wee bit more, but in reality .02 mA mainly is a battery PCB current burp- IF the LED even draws that much current.Quote:

True, the accent pads put out 18mA, but that wasn't the question being asked. JediEngineer has a nonstandard switch that he wants to use, and it doesn't handle much current.
I only noted that some people have accidentally hooked up accent LEDs to the *switch* pads on their boards, and the LED lights up anyhow. The switch pads put out some current, but it's less than 20mA. Since his switch is only rated for 50mA, he shouldn't have any issues using that switch.
If I had one on the bench right now, I'd measure the current. Sadly, I don't have any spare PCs lying around.
