Vibroplex Telegraph Key

Description (Brief):

Telegraph keys are electrical on-off switches used to send messages in Morse code. 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.
