Nuetrik [128]4 years ago
4 0

Explanation:

If there isn't the shorting mechanism, the whole set will be blown if anyhow one lamp burns out. Since having blown out several lamps and then shorted, the overall resistance of the remaining operating lamps will be decreased  resulting in an increased working current that is adequate to blast the fuse.
