ABSTRACT:
A thermal fuse comprises a coiled spring interposed in a stretched condition between two opposed conductors in such a fashion that the spring is imparted with tension and is soldered by a fusible alloy having a specified fusing point. The coiled spring is cut at one portion so that a circuit between the two conductors is broken upon fusing of the fusible alloy due to the action of the coiled spring cut at one portion.
