• Notes
• The explosive growth of telegraph land-line communications after 1844 led to interesting "improvements" in telegraph key design which culminated in the "Triumph Key" patended in 1881 by Jesse Bunell, a telegraph equipment manufacturer who had been a telegrapher during the Civil War. The all-steel lever of Bunnel's "Triumph Key" solved the problem which affected all of the earlier key designs in which the lever would come loose from the press-fit trunnion pin and slide back and forth, left to right, making the key useless.
