Schematic.
All it would take to build a "Reed Switch Oscillator" would be to invert and re-position the Reed switch to the end of the power coil in the schematic below: This is a Kindergarten level project. I'm flabbergasted that these "Nerds" can't handle it! All you'd need to do is switch the polarity of the battery contacts if it failed to start up. "You don't want to try that; It would speed up and run out of control"!
The rotor magnets in the schematic are monopole S pole facing out. The normally open Reed switch has one contact that is fixed, and a second contact that is polarized N and bends. The N pole bending contact is farthest from the magnets in the schematic. That means the end of the power coil facing the magnets would need an electromagnetic S pole to attract the flexible contact away from it's grounding sister when it's energized. This would cause the motor to run in repulsion. The Reed switch in the schematic would need to be turned over when re-positioned on the end of the coil to work correctly. Naturally, the rotor in the schematic would speed up and disintegrate if you hooked it up that way and tried to run it. That's why I designed the "Oscillating Reed Switch" motor rotor with high speed precision ceramic bearings to run inside a protective PVC coupling. It's simple, but "don't try it without first taking the proper safety precautions"!
Another important point is that a North or reversed coil pole will fry the Reed switch by keeping the contacts closed too long. Best to test for correct polarity in advance! Avoid welding the contacts together.
