Bolter Bug Telegraph Key

Description (Brief)
Telegraph keys are electrical on-off switches used to send messages in Morse code. This semi-automatic telegraph key was designed by Royal L. Boulter in the early 1910s. Boulter's patents were ultimately purchased by the Vibroplex Company. 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.
