Novel structure of scram button

The utility model discloses a novel structure of a scram button. The novel structure of the scram button is characterized in that the structure comprises an operating system, a changeover contact system and a control system; the operating system comprises mushroom head operating face, a mushroom head connecting member connected with the mushroom head operating face, a mushroom head housing connected with hooks of the mushroom head operating face, and a manipulator connected through hooks of the mushroom head connecting member; the changeover contact system comprises a plastic housing, an installation seat connected with the plastic housing through hooks, and a normally-closed sliding seat, a normally-closed static contact foot, a normally-closed push rod, a normally-closed dynamic contact piece, a normally-closed push rod spring, a normally-open sliding seat, a normally-open static contact foot, a normally-open push rod, a normally-open push rod No. 1 spring, a normally-open dynamic contact piece and a normally-open push rod No. 2 spring which are connected with the installation seat by a splicing means; and the control system comprises a control panel disposed on one end of the plastic housing, a press button disposed on the control panel, and a pedestal arranged on the tail part of the press button. The operating system, the changeover contact system and the control system naturally coordinate to form the novel structure of the scram button, thus to replace a conventional split structure; the mushroom head operating part and the manipulator of the operating system are connected through hooks, and the changeover contact system is assembled by a splicing means and then connected into the plastic housing by hooks, thereby achieving perfect combination among faces and meeting the ergonomics design philosophy; and the tail part is lead out of the pedestal through a lead so as to form a full closed type super-short tail part, causing no convenience for installation of rear equipment of the control panel.
