Has anyone used a Thumbwheel Switch such as these: http://www.digikey.com/product-search/en?mpart=A7D-106-1&vendor=39
I am interested in changing the internal number strip. For examples I have only found Digit based switches from 0-9, I personally would like to put my own set. I asked Digikey + Mouser techs via Chat and they said I would need a custom order from manufacturer.
Does anyone know how these work? How hard is it to create my own? Yes, I know I can use an OLED screen with two buttons and an ATtiny85 to create my own digital pushwheel switch, however, I would like a thumbwheel where the values/digits/symbols can be printed/replaced.
