ABSTRACT:
A switch breaker includes having a body; a press button having a link; a metal sheet having an electrical contact; a elastic member; a first terminal having a point contact; a second terminal; and a cover, characterized in that a protrudent part is formed on a suitable place on the metal sheet. After one end of the press button is pressed, the insulator does not push the protrudent part of the metal sheet so that the electrical contact contacts the point contact and the switch breaker is at a conducting state. When the current load is too large and the metal sheet is too hot and bent, or when the other end of the press button is pressed and the insulator pushes the protrudent part, the electrical contact is separated from the point contact and the switch breaker is at a nonconducting state. The design of pushing the protrudent part backward by the insulator to move the left end of the metal sheet backward can prevent the occurrence of arc between the electrical contact and the point contact. Further, because the insulator presses the protrudent part and does not contact the electrical contact and point contact, the electrical contact and point contact are not worn away. Therefore, the life of the switch breaker is extended.
