Abstract

An electric fuse, mainly for an incandescent lamp comprising a length of readily fusible electrically conducting material formed with at least one region of reduced cross-section between adjoining regions of larger cross-section, and having around the smaller cross-section region a quantity of electrically insulating material in the form of grains adhering to each other and covered by a protecting coating.
