The switch should include a simple series resistor of a few hundred ohm to protect this pin against over-voltage.

- etaioinshrdlu 7y agoNah it should have a voltage regulator.
- amluto 7y agoIMO the PD chip should be internally protected to 20V, since accidental shorts between the power and CC pins are not implausible.
- chipsa 7y agoThe plug shouldn't wiggle enough to cause a short when fully plugged in, and when you're inserting, the power pin is limited to 5V.
- amluto 7y agoPerhaps, but as we've seen, USB-C power supplies vary in quality :) In any case, protecting against or even 30V should cost essentially nothing. A few series diodes and a resistor should do the trick, no? Diodes are cheap on a CMOS chip.
- swiley 7y agoAfter a few hundred plug cycles it’s probably going to deform enough that it will no matter how correctly you manufactured it.

- bsder 7y agoHow about it should have been an actual USB-C port instead of the horribly broken bodge than Nintendo designed? USB-C PD 2.0 has quite good specifications that take into account the different failure modes and misbehavior that can occur.
- phamilton 7y agoIt is an actual USB-C port on the Switch. The dock on the other hand has the non-standard part: a USB-C male connector that doesn't fit snug. Basically, using a dock is equivalent to plugging a cable that resembles USB-C but isn't actually USB-C.
