Switch and interface: The electric key comes with a sound and light module for simulating telegraph transmission, a metal button switch for easy use, and a 3.5mm audio interface. It can be connected to a radio station and used for training and sending. Anti-slip foot pad: High-quality rubber anti-slip pads firmly grip the desktop during use, preventing sliding during code transmission and providing shock absorption. Suspended flange bearing: Unlike traditional pin-fixed electric keys that feel rough, the suspended bearing offers smooth operation, enhanced durability, and wear resistance. Metal material: Precision-made with high-quality steel and anodized finish on some parts; the contact area uses pure copper to ensure reliable conductivity. Versatile application: Ideal for Morse code enthusiasts, amateur radio, outdoor adventures, or indoor practice. Lightweight design makes it easy to carry with portable radio equipment.
