An electric cigar lighter includes a receptacle for receiving and energizing an igniting unit of an automatic electric cigar lighter, the receptacle having a pair of circuits having respectively a grounding contact and a polarizing contact both of which are engageable with the igniting unit to carry current thereto, and a heat-responsive device comprising a solid state positive temperature coefficient resistor disposed in series in one of the circuits, the resistor being adapted to receive heat from the igniting unit for limiting the current in the one circuit when the resistor attains a predetermined high temperature. |
