In the US, just one SPST should suffice, if it's
in the live wire.
...and you use a three-wire grounded plug (which admittedly
approximately all computer equipment does).
You need DPST switches in much of Europe because there
you find
unpolarized outlets.
And because in some parts of Europe you find balanced mains, rather
than hot-and-neutral mains. (That is, the two power wires are each
hot to ground, 180? out of phase with respect to one another, very much
like what in North America would be a 220V outlet.)
