So please bear with the long explanation, and then make suggestions.
Better yet, suggestions with part numbers!

This is going into a product with small production runs but (hopefully)
a long production life. Hence, I'm primarily interested in things that
I can buy off the shelf, from known, established manufacturers (i.e., no
"Honest Chen's eBay Special", nor even stuff from McMaster-Carr). If I
absolutely must I can have stuff made to print, but I have to believe
that there's something suitable out there.

Imagine a plastic board, 1" by 10" by big. It has a 1/4" deep pocket
milled into the top (the 10" by big part) of it.

Now imagine a box, 6" x 3" x 3" on a 1/4" thick plastic plate. The
plate overhangs the box, and just fits into the pocket in the board.
Put the box into the board, and notice how well it's located from side
to side, and fore and aft, thanks to the fit between the plate and
pocket.

Now turn the board over -- damn, the box fell off. This just won't do.

I'm looking for some suitable gizmo to clamp the plate onto the board,
either with 1/4-turn clamps (the sort that have a tongue that sticks out
to engage the plate), or some sort of overcenter latch.

The box will weigh in at less than two pounds, probably less than one.
So the worst loading that the latches will see is accidental. If
someone doesn't quite disengage them before pulling on the box, for
instance, or if someone drops the assembly on the floor (from waist
height).

It has to look good, be made of materials that can stand salt spray, and
be fairly easy to use by the mechanically inept -- if the user can open
a door, they should be able to work the latches.

Some users will need to unclip the box from the board once every few
years. Other users will need to do so on a daily basis. So the clamp/
latches need to be able to withstand both hard use and neglect, and
still work in the end.

Apparently my babbling is too disjointed. My ideal latch would look like
these, only prettier and not quite so drunken-hobbyist-with-a-CAD-program:

Looks to me that what you're looking for is the button from the old
outhouse door!
