Abstract
In order to prevent erroneous operation caused by shrinking of a thermal pellet due to sublimation or softening of the thermal pellet when current is applied, a thermal pellet type thermal fuse includes a metal casing, a first lead and a second lead leading out from the metal casing, a movable electrode, a thermal pellet, a strong compression spring, and a weak compression spring. Difference in temperature is achieved at the surface of the metal casing by selecting different diameters or wires for the first lead and the second lead, or by providing a heat-radiating plate.
