Definition

UNSPSC 43222701

A component of a telegraph system that originally consisted of two pieces of brass or copper which could be pressed together to complete the electrical circuit or allowed to spring apart using their natural "springiness" to break the circuit. As people developed the need to send messages more rapidly, the designs of keys changed and the evolution of these different designs of telegraph keys is the focus of my telegraph museum exhibits.
