Product Code : SCL-PLE-11355

Scientifc Equipment Telegraph Key is an educational electrical communication apparatus designed for demonstrating Morse code signalling, simple electric circuits, switch operation, current flow, and historical telegraph communication principles. It is suitable for school science laboratories, STEM classrooms, physics practicals, electronics activities, and teacher-led demonstrations.

The telegraph key works as a manually operated switch. When the key is pressed, it completes an electrical circuit and allows current to flow through a connected buzzer, sounder, lamp, or signalling device. By pressing the key for short and long durations, students can generate dots and dashes used in Morse code communication.

Product Description

The Telegraph Key by Scientifc Equipment is a practical classroom apparatus used to explain how early electrical communication systems worked. It generally consists of a lever, contact points, spring return mechanism, adjustment screw, terminals, and a stable base arrangement as per the supplied model configuration.

When the lever is pressed, the metal contact closes the circuit and sends an electrical signal. When the lever is released, the spring opens the circuit and stops the signal. This make-and-break action allows students to create controlled electrical pulses for Morse code experiments and simple signalling circuits.

This apparatus is useful for teaching electricity, communication systems, open and closed circuits, switches, coded signals, electrical pulses, and STEM-based problem solving. It connects physics, electronics, and communication history through hands-on classroom learning.

How to Use Telegraph Key

1. Place the telegraph key on a clean, dry, and stable laboratory table.
2. Connect one terminal of the telegraph key to a suitable low-voltage battery or DC power source.
3. Connect the second terminal to a buzzer, sounder, lamp, or suitable signalling device.
4. Complete the circuit by connecting the remaining terminal of the signalling device back to the power source.
5. Check all connections before operating the circuit.
6. Press the key briefly to create a short signal, known as a dot.
7. Press the key for a slightly longer duration to create a long signal, known as a dash.
8. Use dot and dash combinations to form letters and numbers according to a Morse code chart.
9. Ask students to send and decode simple messages during classroom practice.
10. After use, disconnect the power source and store the apparatus safely in a dry place.
