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!
Certainly something could be designed so a hot and neutral break
("disconnect") is quite safe, but you are right, most
applications are safer just breaking the hot. Plus, breaking
both really is just a waste of money for a more complex switch.
