1. magneto GFCI plug is characterized in that:

  • comprising;

    A housing;

    A magneto actuating mechanism is fixed in the described housing, comprising;

    A bracket component (218) has a crossbeam and the support compression leg and the iron core joint pin that are positioned at the crossbeam both sides;

    An iron core (204) links together with described iron core joint pin, and inserts in the bobbin (209);

    A spring (208) is enclosed within on the iron core joint pin, and is positioned between the boss and bracket component crossbeam lower edge of bobbin (209);

    Broken coil (211) and closing coil (210) are wrapped in respectively on the bobbin (209);

    A permanent magnet (212) is positioned at the position relative with iron core;

    A pair of movable contact spring (206) is positioned at and the relative position of described support compression leg, and can be pressed by the support compression leg, and an end of described movable contact spring is provided with moving contact (205);

    A pair of fixed contact (303) is positioned at and the relative position of moving contact (205), and said structure is vertical with described housing plug plane all;

    Wherein, when closing coil (210) energising produces when making iron core (204) with magnetic force that permanent magnet (212) separates, under the restoring force effect of spring, bracket component (218) moves up and returns to described support compression leg and do not press the position of movable contact spring (206), contacts with fixed contact (303) thereby described moving contact (205) is moved up under movable contact spring (206) elastic force effect.
