I want to know more about this kind of encoder, but I can't find any source (other than wikipedia), where I can get more details about it. Can anyone explain or point me to a source where I can read about it? I want to understand the working principle of mechanical absolute encoder.
Sort of like thumbwheel switches.
Incremental mechanical encoders are used in computer mice and digital control knobs but these usually only have 3 contacts that resolve A and B quadrature signals.
