1. the assembly that constitutes by mechanical lock and temperature-sensitive element, it is used for for example standardization breaker type electrical appliance, and with protective circuit and personnel, it has:

  • -lock;

    it is connected at least one pair of fixed contact and moving contact (8);

    mobile each moving contact (8) that is delivered to a joystick;

    make it be bearing in respectively on the fixed contact and and described fixed contact at a distance of moving between two stable positions of certain distance; and

    comprise a movable contact seat (5), in case be short-circuited in protected circuit or the electricity overload, tripping mechanism (9) can work;

    thereby the upset by described contact base (5) is opened circuit the contact, and-temperature-sensitive element, it is based on a kind of bimetallic element (7), just in case transship, described bimetallic element (7) just makes tripping mechanism (9)/contact base (5) assembly pivotally overturn, described bimetallic element (7) is installed between moving contact (8) and the terminal (1), described terminal (1) is connected in the connector of the line protection device of being furnished with itIt is characterized in that bimetallic element (7) is rigidly connected to moving contact (8), and be connected with conduction that described terminal (1) has a single degree of freedom.
