keyboard nomenclature question

[wolfv]

The end user sees a matrix of printed key caps on a keyboard and calls it a "keyboard layout".
The processor scans a matrix of electrically connected switches.
The key-cap matrix and electric matrix can be different.
Is there a word like "keyboard layout" that applies to the electric matrix of the keyboard?

I am writing a keyboard software and want to use meaningful variable names.
Thank you.

I've heard it referred to as a "switch matrix".

Thanks rowdy.

I just found Deskthority calls it "keyboard matrix" http://deskthority.net/wiki/Keyboard_matrix
I like "switch matrix" .
