Abstract
In the thermal-type overload relay such a construction that a bimetallic strip deforms due to heat produced by an excessive amount of current to actuate a normally closed movable contact which constitutes a normally closed contact, and an operating rod is moved in a predetermined direction to thereby close a normally open contact comprising a normally open fixed contact and a normally open movable contact, there is provided a reset rod moving in the direction perpendicular to the operating rod so that when the reset rod is moved in the direction perpendicular to the operating rod, the normally open fixed contact are caused to move toward the normally open movable contact, whereby the normally open contact is returned to the original position, and the normally closed contact is also returned to the original position by a returning movement of the normally closed movable contact due to the returning movement of the operating rod.
