ABSTRACT:
A circuit overload protective device includes a body having a button pivotally disposed thereto and a bimetallic strip disposed thereto which has a first contact point disengagably contacting a second contact point on the body. A first member and a second member are respectively connected to an underside of the button, wherein the first member has a leg extending therefrom so as to be shifted into a curved recess defined in a first inner side of the body when the bimetallic strip is deformed, and the second member has a distal end thereof connected to the first contact point. A third member is disposed to a second inner side of the body and a spring is biasedly connected between the first member and the third member.
