Re: USB controlled mains switch

Lars,

The high-voltage tracks are MUCH fatter than the low voltage tracks
on the PCB, as you can clearly see in the photo of the underside of
the board,

Thick tracks are current, not voltage related.

And by the way, I didn't see those images the first time around : I've got
all third-party (domain) content blocked by default.

and high and low voltage sections of the board are well separated.

How many low-voltage lines do you seee going to the relays at the underside
?   I see just a single one.   And that means the topside has the rest,
which I can't see.

And do remember there is a 30 Watts rating mentioned.  Which one should we
believe ?  That one, or the other, 2200 Watts one ?

I can guess a bit, but I'd rather not when letal voltages are in play. :-|
