I'd definitely say electrons propagate through wires to carry signals. The electrons charge the gates on the fets which opens or closes the channel, which allows electrons to flow through another wire. I wouldn't say it's terribly explanatory tho

Although your light turns on very quickly when you flip the switch, and you find it impossible to flip off the light and get in bed before the room goes dark, the actual drift velocity of electrons through copper wires is very slow. It is the change or "signal" which propagates along wires at essentially the speed of light. refer https://en.m.wikipedia.org/wiki/Drift_velocity https://en.m.wikipedia.org/wiki/Drift_velocity
