It's unfortunate, but most of these are encoded in one way or another. I need raw switches in a 4x5 matrix. I can even use unconnected switches. However, I want a 4x5 array of switches so they're arranged

C D E F <=
8 9 A B =>
4 5 6 7
0 1 2 3 enter

There's an involved history to this, but, suffice it to say, the keytops should be moveable and still available. That way, when the legends are worn off, which my original didn't allow, but which happens within a few weeks with modern keyboards, I can replace them.
