Abstract

In the protector, a push button is movable pivot jointed to opening of box body. One end of push button is extended to bunt one end of a contact piece, and the other end of the push button is inner pivot jointed to an interlock piece. The interlock piece makes pivot joint axis possible to be rotated and swung to the push button relatively. End part of the interlock piece is bunted to the other end of the contact piece. Swing caused by pressing push button makes one extended end of push button drive one end of a contact piece, or makes the other end of the interlock piece eject the other end of the contact piece so that two ends of the contact piece are bounced up and down. Thus, on/off states of circuit loop are formed. When push button is in on state, the contact piece is not restricted by the interlock piece, or the contact piece can be bounced freely. Therefore, if current is overloaded, the contact piece is inverted bounced caused by heat so as to form off state of circuit.
