When a current flows through the main circuit, a current also flows through the conductive wire 3 electrically connected to the main circuit, and it is known from the principle of electromagnetic induction that a magnetic field is generated around the conductive wire 3 to magnetize the inner electromagnetic soft iron 2 to form an electromagnet and the upper end of the electromagnet shows an S-pole.

When the current in the main circuit is just overloaded due to excessive working electrical appliances in the main circuit, so that the current in the main circuit is increased and reaches the safe current magnitude set by the main circuit, as can be seen from the above, the magnetism of the electromagnetic soft iron 2 becomes strong, the attraction force to the annular magnet 4 outside the electromagnetic soft iron 2 becomes strong, and the annular magnet 4 is rotatably connected with the housing 1, so that the N pole of the annular magnet 4 is close to the S pole of the electromagnetic soft iron 2 at this time, that is, the annular magnet 4 rotates counterclockwise.

When the user closes the electrical appliance to reduce the current in the main circuit to be below the safe current, the same as the above principle, the magnetism of the electromagnetic soft iron 2 is reduced, the elastic force of the spring 13 is greater than the attraction force of the electromagnetic soft iron 2 to the annular magnet 4, the sliding block 7 rotates back under the action of the spring 13, namely, the annular magnet 4 rotates back, the conductive block 6 is not in contact with the conductive strip 10, and the warning light 19 is turned off.

When the main circuit is short-circuited, the current in the main circuit is rapidly increased, the annular magnet 4 rotates anticlockwise with a larger rotation angle in the same way as the above, so that the N pole of the annular magnet 4 is opposite to the S pole of the soft electromagnet 2, and at the moment, the annular magnet rotates in the same way as the slot 8 arranged on the annular plate 5 and rotates to be opposite to the latch rod 14.

The plug rod 14 is opposite to the slot 8, the plug rod 14 moves upwards under the action of the spring 13 on the lower side of the plug rod 14 and is inserted into the slot 8, the moving switch 15 fixedly connected with the plug rod 14 moves upwards along with the plug rod, two contacts 16 on the lower side surface of the moving switch 15 are out of contact with two contacts 16 on the upper side surface of the main circuit switch 17, the two contacts 16 on the lower side surface of the moving switch 15 are electrically connected with the main circuit, the two contacts 16 on the upper side surface of the main circuit switch 17 are respectively electrically connected with the main circuit, and the main circuit between the two contacts 16 is.
