Re: What are the odds?
Good idea.
The Germans (or Chinese) had thought of that. The button, which is located on, and sits proud of, the mating surface, fits into a carefully crafted recess in the door itself, meaning that the cover would need to fit into the space between the button and the recess, in order for the door to close.
I haven't crafted the custom cover yet :-)
I'm puzzled that someone even thought an on-off switch was necessary on a refrigerator. At least, they put it high enough so that inquisitive little fingers couldn't reach it.
