Object Details
- Fluharty, William G.
- Description (Brief)
- Telegraph keys are electrical on-off switches used to send messages in Morse code. A semi-automatic key repeated the Morse code dots rapidly, much like holding down a key on a keyboard for repeated letters. This motor-driven, semi-automatic telegraph transmitter from 1923 was used for sending Western Union cablegrams from New York to San Francisco through thirteen repeaters. The wire distance was over 3,000 miles.
