Structure of ground fault circuit interrupter

An improved structure of a ground fault circuit interrupter, a leakage protection action mechanism being disposed inside the ground fault circuit interrupter, the leakage protection action mechanism including a sleeve, a permanent magnet fixed at a position of one end of the sleeve, a soft magnet slidable in the sleeve, an elastic mechanism connected between the soft magnet and the sleeve and an action coil disposed outside the sleeve, and the ground fault circuit interrupter being further provided with a reset button capable of triggering the action coil, wherein

• a locking arm, which is provided with a stop surface, is also disposed inside the ground fault circuit interrupter, and a support body fixedly connected to the soft magnet is provided with a stop portion which can interfere with the stop surface that is moving downward;
• the locking arm is also connected to an elastic element which in a normal state moves downward the stop surface of the locking arm to interfere with the stop portion of the support body so as to stop the soft magnet from moving toward the permanent magnet;
• and
• the locking arm can also be pushed down and driven by the reset button to moves upward the stop surface to, so that the stop portion no longer interferes with the stop surface.
