the claim

Polarized plugs with one wider blade are designed so that an appliance's switch and fuse interrupt the hot conductor rather than the neutral conductor.

Is it true that polarized plugs with one wider blade are designed so that an appliance's switch and fuse interrupt the hot conductor rather than the neutral conductor?

Unclear. Two sources touch on the underlying safety principle that switching should be confined to the hot conductor and that neutral continuity matters, but neither addresses polarized plugs or the wider-blade design, so the specific claim is only partially covered.
