The telegraph key is the tool with which the telegraph operator sent the impulses from the transmission station following the Morse code. {

By pressing the button only for a moment, one point was obtained, pressing it for more time a line was obtained, if it was not pressed, the rear part of the button touched a contact that established a connection with the receiving station which could in turn send a message. {

Today the telegraph key is still used by radio amateurs. In the modern form, the manipulator, as is called in jargon, consists of a lever that can be pushed sideways in the two senses. If the lever is pushed in one direction, a special circuit generates a point, if moved in the other generates one line. In this way the typing speed increases considerably and the duration of points and lines is determined with great precision. {
