Wait, if you press the key for ‘k’ and the three way switch moves from lightbulb contact to battery contact. As the video explains the letter is rewired from one letter to another letter, say ‘x’, and when the circuit returns to the three-way switchs it’s now directed to the letter ‘x’ which is not pressed and in the lightbulb contact position.
So what happens if ‘k’ randomly returns to itself and the switch is in the battery contact position and not the lightbulb position—no light?
- mbauman 5y agoThe reflector ensures that's not possible. There are 26 independent circuits that go from the key switch through the pegboard through the rotors and to the reflector. Pressing a key makes one of those 26 circuits hot. Now attach the reflector: it necessarily connects that hot circuit to a different one.
- geiser 5y agoThe rotor is "per se" designed to never let this happen. The combination from the beginning to traverse all 3 switches is 1:1, so unless the reflector connects to itself, it will never actually collide. Or let's put it differently. Imagine just 1 switch, as it's the same reasoning. It will always change the letter, and will never return the same letter, given that the first switch always follows the key you are pressing.
