摘要 |
Conductive caps are respectively put on both ends of an insulating cylindrical member and a pair of cup-shaped contactors are disposed in the insulating cylindrical member in a manner to be movable relative to each other. A repulsive force is provided by a pair of biasing elements located between the pair of cup-shaped contactors through a fusible member to electrically interconnect the conductive caps. When the fusible member is fused at a predetermined temperature, the biasing force of one of the biasing elements weakens and the biasing force of the other biasing element increases to move the pair of cup-shaped contactors toward each other, thereby to electrically disconnect the conductive caps from each other.
