I insist you remove this example from your comment.
The stepping of the Strowger switch in response to the dialled number is in
response to the number of dial pulses. The digits "1"-"9"
generated that number of dial pulses and so, in this context, the digits
represented the number of pulses. (Actually, nothing has changed. One can still
set modern phones to dial pulses rather than two tone codes. The exchange should
still respond.) The digit "0" actually stood for '10' (something about
exchanges counting '0' pulses).
Could you replace it with the calculator buttons? Does the relationship of
symbol to actual numeric value harm the dissertation?
If not, try TV remote controls.
