So, how are you supposed to wire a switch on equipment meant to be used
on hot/neutral (120V) and hot/hot (208/240V) power inputs, like
autoswitching computer power supplies?

However, a DPST (breaks both live and neutral) is safer IMHO
NO,NO,NO!!!!!!!!!!!!!!
This can potentially leave a circuit floating, wich can be much more
dangerous. Try to HI_POT test a device in this configuration, and you
may very well let the "magic-smoke" out. If you are switching on the
raw power side, the neutral should always remain connected. In fact
this is code for many (most/all) CE/UL approval stamps!
