Vibroplex Champion semi-automatic Morse code key, also known as a "bug" key, used by telegraphers and amateur radio operators. It automatically generates a rapid series of "dits" (dots) when the lever is pushed to one side, reducing operator fatigue. "Dahs" (dashes) are made manually by pushing the lever the other way. The key features a solid metal base for stability and adjustable tension for personalized feel.
