Ive been on a shopping spree lately and I purchased a few of the mini meters and thumbwheel switches shown in the pictures. When using things like this in a project, my first idea is simply to cut openings in a project box with a dremel to mount them. However, they appear to be designed to fit into some sort of latching receptacle, and i'd like to know if there's a standard for this sort of thing (like dupont or 4mm jacks)

I do not know if there is a standard.
They are designed to push fit and hold themself in place without additional nuts and bolts.
The plastic latches are there to hold them in place.
A screwdriver can be used to depress the latches if you need to take them out again.

The thumbwheel switches in the first picture need the endcaps to be held in place, they have some locking pins to hold on each other.
The panel meter has the mentioned latches.

The standard 1/4 DIN cutout or opening is popular for industrial instrumentation and controllers, and 1/32 DIN for digital panel meters from china (I think).
It's basically hell to cut one. I use a nibbler or there are specialized punches (Alfra) that I dream of buying but they are very expensive. The thumbwheel cutout looks like a custom size.

Sometimes when I run into a situation like that with panel mounted stuff...hot melt glue is the answer. It holds parts in place, and can be cut out if you need to remove the part.
