In today's "soft power switch" world,
you're lucky if there's a mains
disconnect switch on the power supply at all.
Most mains wall socekt outlets over here have internal double-pole
swithces which are sueful if the device doesn't have a real mains swtich :-)
For countries where that's not the case (and indeed over here if you are
plugging the machine into a multi-way mains adapter), it's quite useful
to make up a mains plug to IEC socket lead with a double spole swithc
somewhere along it. Add a neon indicator too ifyou like. I have one that
I use when I am repariign something and don't want to use the internal
mains swich, perpahs because it weoule be difficult to handle it without
accidentally tocuhign the terminals.
