I need to partially rewire my apartment. I am tempted to replace some old
double-switched sockets with those that incorporate USB sockets.
Some are described as Switched USB Socket 13A 2-gang + 2 USB.
Can I assume that the USB sockets on these are actually switched and carry
no current until a plug is inserted?
If you have any experience of these things I would appreciate the benefit of
Somewhat OT to your question, but what is the RFI like from these
unswitchable USB power supplies? There's an interesting video here
showing the interference from a cheap and nasty power supply compared to
a branded one. OK, it's not USB but the principle is the same. What I
found interesting was that there was a fair amount of RFI even when the
rubbish SMPS was unloaded. That's somewhat similar to the situation with
these built-in mains-socket USB power supplies. I just hope they're well
filtered. At least you can unplug a noisy wallwart!
