Claims

[Scope of utility model registration request]

A movable contact having a fixed contact, a movable contact provided at a distal end to make contact with and separate from the fixed contact, a proximal end of the movable contact being pivoted to the distal end so that the proximal end serves as a rotation fulcrum, and a distal end. A contact holding plate whose end surface elastically abuts an interlocking member that responds to the on/off position of the handle, and an opening spring that elastically biases the contact holding plate, form an E shape. a fixed yoke, and a first position in which the proximal end is swingably supported by the contact holding plate so that the proximal end has a corresponding portion with each end surface of the fixed yoke between the proximal end and the distal end, and is not attracted to the fixed yoke; a coil connected in series to the movable contact and wound around the central leg of the fixed yoke; and a coil suspended between the movable contact and the first armature, a reversing spring that biases the movable contact in the closing direction in the position and in the opening direction in the second position; a latch link that responds to displacement of the bimetal; and a trip link that engages and disengages with the latch link and is linked to the handle. . a handle for engaging said trip link with said latch link upon actuation from an off position to an on position.
