American Vibroplex Telegraph Key

Description (Brief):

Semi-automatic keys like this "American 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.

Description (Brief)

King & Company produced this key under license from a company that worked with Horace Martin, inventor of "Vibroplex" semi-automatic key.
