The Vibroplex semi-automatic
telegraph
key, or bug, is a
mechanical morse code telegraph key with side-to-side
movement. Patented by Horace G.
Martin in 1907,
it allowed for
faster code transmission and eliminated the physical
damage to the operator's arm ("glass arm") caused by constant up and
down motion when using
a hand
key. 1944 WWII Deluxe #4 View These Keys
