とする自己保持形サーマルプロテクタ。A fixed contact plate having a fixed contact and a movable contact plate made of a springy metal having a movable contact at its tip are housed in a case so as to face each other so that the movable contact is normally in pressure contact with the fixed contact. A positive characteristic thermistor having electrodes on opposing main surfaces is arranged on a fixed contact plate, and one electrode is electrically connected to the fixed contact plate, while the shape changes due to heat and a part of the positive characteristic thermistor has the above positive characteristic. A thermally responsive element that contacts another electrode of the thermistor to lift the movable contact plate and separate the movable contact from the timed contact is attached to the movable contact plate above the positive temperature coefficient thermistor, and the thermally responsive element is deformed. A self-holding type thermal protector characterized in that the movable contact is maintained in an open state from the fixed contact by energizing only the positive characteristic thermistor.
