We have two Morse Code Key Machines in our Technology through Time Collection.
Morse keys were used to send telegraph messages using a type of communication called Morse Code.
The machine worked using a bar with a contact underneath. When the bar was pushed down, the circuit was completed, and this meant that an electric current could flow. This type of Morse Key Machine was used by Post Office telegraph operators in Britain for many years. Morse Code consists of a series of long and short signals which could be translated into letters and words, and that written out as a telegram.
