A fuse holder tester (50) is arranged with a plurality of conductive, resiliently mounted contact fingers (51, 52), for making electrical contact with leads (11, 12) embedded in the walls of the fuse holder (10). The tester also includes a spring-loaded probe (58) arranged to make contact with a third lead (13) located at the base of the fuse holder, upon insertion of the tester into the holder. In one example, a testing assembly (70) is provided, having six of the testers (50) capable of being simultaneously inserted into a typical fuse block (30) having six of the fuse holders (10).

Apparatus for providing electrical contact with a plurality of leads individually located in the walls and at the base of a fuse holder socket shaped to accept a tubular fuse, the apparatus comprising: a tubular body arranged to fit into the socket; a base attached to one end of the body; a plurality of free ended spring fingers of conductive material extending from the base along the length of the tubular body, the free ends of the spring fingers projecting outward from the body and capable of moving toward and away from the body; an electrical lead extending through the center of the body to the base; and a spring-loaded probe extending from the end of the body opposite the base and connected to the central electrical lead; the parts being so constructed and arranged that, when the body is inserted into the socket, the plurality of spring fingers are initially cammed inwardly by the walls of the socket, following which the plurality of fingers spring outwardly to physically and electrically contact associated ones of the plurality of leads located in the walls of the socket and, as the probe comes into contact with the lead at the base of the socket, it is forced rearward with respect to the body so as to assure good electrical contact.
