Product Description
Telegraph Key (Tapping Key), mounted on a solid plastic base, measuring 11 cm x 5 cm.
Includes two contact screws/ knobs to simplify wire connection.
Invention of telegraph and Morse code was the first step towards modern communication systems. All you need to make a telegraph station model is a tapping key, batteries and a simple electromagnetic sounder (clicker) that you can make at home.
Making a telegraph circuit is a good way to learn more about electricity, electromagnet and digital communication.

Miniscience Telegraph Key
Bought some of these for my niece's children to use for learning Morse Code. (Ages 6-13) Very good, simple design and good 'action' on the key.
