Vibroplex Telegraph Key

Description (Brief)
Semi-automatic keys like this "Vibroplex" automatically produced rapid morse code dots by using a weighted pendulum to quickly make and break contact in the electrical circuit. The operator would make the dashes manually but could send much faster than with an ordinary key. Operators often purchased their own keys. This unit belonged to Western Union operator F. L. Currie.
