Abstract
A structure of a ground fault circuit interrupter includes a locking arm, which is provided with a stop surface, disposed inside the ground fault circuit interrupter, and a support body fixedly connected to a 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, and under a normal state, the elastic element moves downward the stop surface of the locking arm to interfere with the stop portion of the support body, so that the soft magnet is prevented from moving toward a permanent magnet The locking arm can also be pushed down and driven by a reset button to move upward the stop surface, so that the stop portion and the stop surface no longer interfere with each other.
