A temperature sensitive circuit breaker includes two contacts electrically mounted on a circuit board and an insulating pivot seat attached to the circuit board between the two contacts. A lever has a first end pivotally connected to the pivot seat and connected to one of the contacts, and a second end electrically connected to the other contact. A non-metallic expansive rod is mounted on the circuit board below the lever to push the lever upward to make the second end of lever separate from the contact when a high temperature on the circuit board is transferred to the expansive rod. The breaking member causes a high temperature to melt itself when a current passes through the breaking member to open a circuit on the circuit board.
