The trick is to convert from 1 of n to binary.

The attachment is an extract for one of my designs. I've converted 1 of 10 to binary using a 2 gang rotary switch.

It could be done with a one gang switch by:-

1. using more diodes, or
2. using a Priority Encoder IC.

In the case of a one gang, 4 position switch (ie. n = 4 ), all you need is 2 diodes and 2 resistors.

But if you use a 4 position, 2 gang switch, all you need is 2 resistors.

EDIT, I mis-read your request. You want 6 LED patterns.

So you can do it with a 2 gang 6 position switch and 3 resistors as per the 0 ~ 5 positions in the attachment,

You can use a single ADC to select different subroutines with a multiple point potential divider. Read the ADC value to call different subroutines.
