The telegraph key, an essential component in early telegraph systems, was developed by Samuel Morse and Alfred Vail in the 1830s. They created the device as part of the Morse Code system, which allowed for the transmission of messages over long distances using electrical signals. The key itself is a simple switch that opens and closes an electrical circuit, enabling the transmission of dots and dashes that represent letters and numbers.
