Abstract

The invention discloses a normally closed structure of a magnetically controlled switch. The normally closed structure is characterized in that the normally closed structure comprises a base, an inner magnet, an actuating rod, a static contact piece, a movable contact piece and a plastic cover, wherein the base comprises an inner magnet embedding hole, an actuating rod hole, a static contact piece hole, a movable contact piece hole, a positioning mounting hole and a base connecting hole, the inner magnet is embedded in the inner magnet embedding hole, the actuating rod is embedded in the actuating rod hole, the static contact piece is embedded in the static contact piece hole, the movable contact piece is embedded in the movable contact piece hole, and the plastic cover is arranged at the surface end of the base. The distance between inner magnet limiting support pillars is equal to the width of the inner magnet, the inner magnet moves up and down in the inner magnet embedding hole in the vertical direction, a round hole is formed by the inner magnet, a matching arc and an actuating rod hole connecting face, the diameter of the round hole is equal to that of the actuating rod, and the normally-closed structure of the magnetically-controlled switch, which is compact in structure and accurate in guide contact, is provided for users.

Description

technical field [0001] The invention relates to the technical field of magnetic control switches, in particular to a normally closed structure of a magnetic control switch. Background technique [0002] Magnetic switches are mainly used in large and small household appliances, washing machines, refrigerators, noodle machines, cooking machines, coffee pots and other electrical equipment. , base, rivet, moving contact, moving insert, action rod, static insert, static contact, moving contact, and plastic cover. Its working principle: when the outer magnet is close to the inner magnet to a certain distance, the same The principle of mutual repulsion pushes the inner magnet to a certain distance. At this time, the repulsive force between the two magnets overcomes the elastic force of the moving contact piece to separate the moving contact from the static contact, and the circuit is disconnected; when the outer magnet moves a certain distance, the two magnets The repulsive force ...
