Disclosed is a miniature breaker which progressively reduces contact resistance and permits further miniaturisation by appropriately maintaining the contact locations of a fixed contact point and moveable contact point. The breaker is equipped with a fixed contact point (2), a moveable contact point (3), a bimetal (4) and a case (6), where the moveable contact point (3) is equipped with a second elastic member (35) possessing a lower elastic coefficient than a first elastic member (34), and a fixing member (33) disposed between the first elastic member (34) and second elastic member (35) which is fixed by the case (6). |
