Alfred Vail

Alfred Lewis Vail (September 25, 1807 – January 18, 1859) was an American machinist and inventor.

Armature (electrical)

In electrical engineering, the armature is the winding (or set of windings) of an electric machine which carries alternating current. Telegraph sounder and armature (electrical) are Electromagnetic components.

Electric battery

An electric battery is a source of electric power consisting of one or more electrochemical cells with external connections for powering electrical devices.

See Telegraph sounder and Electric battery

Electric current

An electric current is a flow of charged particles, such as electrons or ions, moving through an electrical conductor or space.

See Telegraph sounder and Electric current

Electrical telegraph

Electrical telegraphy is a point-to-point text messaging system, primarily used from the 1840s until the late 20th century. Telegraph sounder and Electrical telegraph are telegraphy.

Electromagnet

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Electromechanics

In engineering, electromechanics combines processes and procedures drawn from electrical engineering and mechanical engineering.

See Telegraph sounder and Electromechanics

Magnetic field

A magnetic field (sometimes called B-field) is a physical field that describes the magnetic influence on moving electric charges, electric currents, and magnetic materials.

See Telegraph sounder and Magnetic field

Morse code

Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. Telegraph sounder and Morse code are telegraphy.

Relay

Telegraph key

A telegraph key or Morse key is a specialized electrical switch used by a trained operator to transmit text messages in Morse code in a telegraphy system. Telegraph sounder and telegraph key are telegraphy.

See Telegraph sounder and Telegraph key

Telegraphist

A telegraphist (British English), telegrapher (American English), or telegraph operator is an operator who uses a telegraph key to send and receive the Morse code in order to communicate by land lines or radio.

See Telegraph sounder and Telegraphist

Telegraphy

Telegraphy is the long-distance transmission of messages where the sender uses symbolic codes, known to the recipient, rather than a physical exchange of an object bearing the message.
