When the spring moves down, the current flowing from the middle pin contact through the steel spring and the two coils (the 2nd mounted below the plate) is shut off, the spring rebounds and makes again contact with the middle pin, which repeats the procedure. Note the paper covered cylinder with the brown handle: this is the only mean to lower or rise the intensity of the high voltage impulses delivered through the two contacts (+ and -). | |
