That setup (one side of 240 line switched) is done all the time in the
internal wiring for a kitchen oven. I'm not defending it as the safest,
just that it is a common way to do it.

Think this through a little farther. You don't have one wire carrying 240V as
you illustrated. You have two: L1 and L2.

Finish your drawing -- show where you're going to connect the L1 and L2 leads
to that switch.
Sigh:

L1 --- _________/ ___________

|__/ __|
240 LOAD

L2 --- _________________________

Sigh:

So L2 will always be supplying 120V to the load, even when the switch is off.

Does that sound safe, prudent, or wise to you?
