Telegraph sounders are devices used in telegraphy to receive and display Morse code messages. They are part of the supply class Telephone and Telegraph Equipment, which falls under the supply group Communication, Detection, and Coherent Radiation Equipment.

Telegraph sounders consist of an electromagnet and an armature. When an electrical current is passed through the electromagnet, it creates a magnetic field that attracts the armature. This movement produces an audible clicking sound, hence the name "sounder." The armature is connected to a lever that is used to mark dots and dashes on a strip of paper or tape.

In telegraphy, Morse code is used to represent letters, numbers, and other characters. A dot represents a short signal, while a dash represents a longer signal. When a telegraph operator receives a message, they interpret the dots and dashes and use the telegraph sounder to transcribe the message onto paper.

Telegraph sounders were widely used in the late 19th and early 20th centuries for long-distance communication before the advent of telephones and modern digital communication systems. They played a crucial role in enabling rapid communication across long distances, such as in the operation of telegraph lines and the transmission of important messages.

Today, telegraph sounders are primarily used in historical reenactments, museums, and educational settings to demonstrate the technology and techniques used in early telegraphy.
