An illustration of a telegraph key. The key is made of metal and has a green body with a blue handle on top. The handle has a curved shape and appears to be made of a shiny material. On the left side of the key, there is a small knob with a screw, which is likely used to adjust the tension of the handle. In the center of the image, there are two smaller knobs, one on each side, which are used to hold the key in place while the other on the right side is used to operate the key. At the bottom of the device, there appears to have a wooden base.
