Object Details
- Mecograph Company
- 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. The operator still keyed the dashes but could work much faster. The Mecograph Company created a right-angle semi-automatic telegraph key around 1906. They competed with Horace Martin's Vibroplex Company until Martin purchased Mecograph in 1914.
