Proportional you mean with potentiometer? This is tough for me my friend!

I need to know if this switch exists.

You can use 2-3-4 or as many as op-amps as comparators or even a/d converters to have as much outputs as you want from a potentiometer. it is very easy even for an amateur. Give it a try. We can help!

The op-amps? Check for an analog to digital converter in the archive. It is extremely easy
