I have a schematic for something - including some thumbwheels, meaning those BCD coders, with 2 buttons... so you can count from 0 to 9, and have 4 outputs.... what is the symbol for that?
And - if anyone can tell - what is a thumbwheel in Danish or Estonian?
I'd just make a box with 5 pins named 1, 2, 4, 8, and C. If I was feeling artistic, I might try to draw something that looked like the face of the switch in the box.

Why encourage them to be stupid? If they can't get it from the obvious drawing of four switches in a box with a pair of plus/minus buttons on it and a standard acronym for Hexadecimal or Binary Coded Decimal, I doubt they could reliably comprehend the difference between an DPST and an DPDT switch, and they should give up their job for someone who can.
Labelling the pins will be up to you, as the orientation will depend on the most convenient fit in your diagram.
In the vague hope that someone will these symbols useful, I have them in vector form, in PDF files, so they can be scaled and printed accurately.
