This key is a Morse code training key that relates to the field of wireless communication technology, including a key base, an integrated audio-visual circuit board set at the key base, a tapping table, a tapping component, and other components. While having the same function of simulating Morse code transmission, it can simplify the overall mechanical structure, provide convenience for use, ensure training effectiveness, and be used for beginners to learn or demonstrate.

Traditional electric keys have a large volume and heavy weight. When learning to send messages or demonstrate, it is necessary to connect a telegraph trainer or radio station in order to produce sound and light. Users urgently need an electric key that can spontaneously sound and light, is lightweight, and easy to carry. The K8 training key is designed and produced to meet the above requirements, with light weight, convenient portability, and two working modes of sound and light demonstration and radio output.

Operational principle

1. Turn the mode conversion switch of the sound and light demonstration mode to the on position. When the key is pressed, the integrated sound and light circuit board emits sound and light demonstration. In this state, the audio socket has no output;

2. Turn the radio output mode conversion switch to the off position. When the button is pressed, the integrated sound and light circuit board does not emit sound and light demonstrations. In this state, the audio socket has output and can be connected to devices such as radio stations and trainers to send messages for operation;

Main technical indicators

1. Material: The base is made of rosewood, the main structure is made of 304 stainless steel, the knocking table and other components are made of brass, and the main connecting parts are made of T2 purple copper;

2. Power supply voltage: 3V (one 2032 lithium battery);

3. Volume: 135 * 65 * 50mm;

4. Weight: ≈ 230g;

5. Output interface: 3.5mm audio socket;

Precautions

1. When installing the battery, the pressure spring may cause the negative pole of the battery to "-", and reverse installation may cause the equipment to not work;

2. Only 2032 lithium batteries can be used, other batteries may be damaged or not working due to different voltages;

3. If not in use for a long time, the battery should be removed and replaced at least every six months to prevent battery leakage and damage to the keys
