An electric fuse constructed of a subassembly including a blown-fuse preassembly. The preassembly includes a stationary structure including an indicator housing having a chamber therein, an indicator pin mounted in the chamber for movement from a nonindicating position to an indicating position, an indicator spring mounted between the indicator housing and the indicator pin so as to bias the indicator pin from the nonindicating position to the indicating position, and a flexible indicator restraining wire having a first portion engaging the pin for restraint and, on respective sides of the first portion, second and third portions extending out of the indicator housing, the wire being in tension against force provided by the indicator spring to the indicator pin, the indicator wire restraining the pin in the nonindicating position and maintaining the spring cocked, the second and third portions being secured under tension by rigid bonding to the stationary structure. The subassembly includes a pair of insulator plate spacers, one of which carries the indicator housing, a pair of elongated conductors that are spaced by the plate spacers, and a multiple-element conductor array including a pair of spaced, substantially parallel, elongated base members and a plurality of substantially parallel fusible elements integral with and between the two base members, the base members being positioned in respective grooves in and being in electrical contact with the conductors.
