Just helped do an installation of a tankless water heater for a
customer. My part of it was wiring the heater (it's got electric
ignition). It's wired to a switch inside the house. The customer is
concerned that the switch could be mistaken for a light switch and
turned off, as am I, so I looked for some kind of cover for it with no
luck. I was hoping to find something like the little rectangular metal
box covers that one sees on furnace switches; you know, the ones that
flip up to. The only ones I could find, however, have a switch and a
fuse mounted in a duplex box, with the cover over the fuse, not the
switch (I don't need a fuse anyhow).

These little covers would be perfect. Are these available anywhere for
use with switches? I'm thinking either a cover plate that has the safety
cover built into it, or a cover that could be screwed over an exisiting
switch plate.

Where's the switch located? Is it actually in a location where it is
conveniently accessible and actually could be mistaken for a light
switch?

Yes, it is. See below.

If it is, I humbly suggest it was placed in the wrong location. I have
a switch for the ice wires on my house and I purposely placed it where
it won't ever be mistaken for a light switch *and* labeled it as to
it's purpose. The idea is "intention". Based on it's location and
labeling, I seriously doubt anyone would flip this switch "just to see
what it would do".

Point taken. It ended up where it is because, well, there was an
existing outlet that I took power from, and it was convenient (i.e.,
easiest) to put the outlet and the switch in a box in the same location.
I suppose what a guy should have done was to put the switch in a
separate box, out of reach and labeled. Next time.

I think I'm going to go with the "baby-proof" solution. Cheap,
effective, and nothing to lose.
