ABSTRACT:
This invention relates to an operation-indicating device for fuse cartridges for electrical protection, of the type comprising a plunger formed by a pusher element which is retained against a resilient actuating member by a secondary fuse wire connected in parallel with the wire or wires or fusible elements of the cartridge, characterized in that the base of the plunger cooperates with the conventional portion of the reduced section of the secondary wire, and an intermediate piece is in contact with the wire on either of said portion which is arranged so as to behave in non-conductive manner with respect to low-voltage current which passes through this wire and in conductive manner when the reduced section is fused so that the high-voltage current is transmitted to the two parts of the secondary wire disposed on either side of the portion of reduced section.
