This a test for you. Draw the diagram of LM317 using spst switches.

I'm still figuring out how to do it. But it can be done.

Draw the circuit that uses a potentiometer.

Then think of the potentiometer as a series of fixed resistors, and the wiper as a switch moving along those resistors. How can that switch be replaced by a series of switches?
