These rotating bar switches obviated the local operator to complete a local call. The switches connected physical wires, circuits, to make an electrical connection to a specific residence or business set of wires. No more operator plugging A to B. The plug (then switch) connected a pair of wires called tip and ring, a terminology that persisted for decades, even when the technology advanced to digital switches, as did the term twisted pair.
Rings were caused by 40 volts DC flowing down that circuit . That voltage could knock you on your butt.

Rings were caused by 40 volts DC flowing down that circuit from a huge rack of dry cells at the local switching station.

Rings were caused by 40 volts DC flowing down that circuit. That voltage could knock you on your butt. 100V DC pulsed at 20 Hz.
Plenty enough to get your full undivided attention...
