Abstract: A fuse holder (20) is provided that can be installed in the place of a dropout fuse element in an electrical insulating unit (1). The fuse holder has an elongate electrically insulating body providing at least one electrically insulated elongate fuse housing in the form of a passage (21) associated with the body and adapted to receive a fuse wire (22) held under tension therein. The body can be installed in such insulating unit as a replacement to an existing dropout fuse element (5) and itself provides contacts enabling such a conventional dropout fuse element to be installed in the fuse holder body from which it can drop out when the fuse is blown. A switch arrangement is provided for maintaining a fuse in the passage in an inoperative condition whilst a dropout fuse element is functional and for automatically closing an electrical circuit through a fuse installed in said passage when the dropout fuse becomes blown and drops out of the fuse holder.

Abstract: A holder (10) for a fuse (18) of the type typically used in automobile and marine applications. The fuse includes a fuse element encased within a generally rectilinear insulative fuse body (20), with a pair of parallel coplanar conductive blades (22, 24) in contact with opposite ends of the fuse element and extending out the fuse body. The holder is a unitary molded insulative plastic piece having a base member (12), a capture plate (14), and a cover member (16). The capture plate and cover member are hingedly secured to the base member on opposite sides thereof, with the capture plate adapted to overlie the base member and the cover member adapted to overlie the capture plate. The base member includes pockets with retention wings (50) for holding wire- terminating receptacles (28) and the capture plate locks the receptacles in place by means of blocks (62) extending into the pockets. The capture plate includes apertures (58, 60) aligned with the receptacles for receiving therethrough the fuse blades.

Abstract: An automotive fuse inserting and attaching apparatus that has an aligning portion for aligning automotive fuses to be inserted and attached into a fuse box. The aligned automotive fuses are aligned in the same arrangement they assume when inserted and attached within the fuse box. The automotive fuse inserting and attaching apparatus includes a feeding portion for feeding predetermined automotive fuses to the aligning portion. The automotive fuse inserting and attaching apparatus further includes a hand-type inserting and attaching portion that is separable from the feeding portion, for inserting and attaching a group of automotive fuses into the fuse box by conveyably clamping with one hand the group of automotive fuses aligned by the aligning portion.

Abstract: A fuse switch includes a fuse element having a plurality of radiating arms, each arm being positioned, in its turn, above circuit contacts in the switch. The fuse is mounted for rotation, and is controlled by a rachet wheel drive mechanism to change its position. An indication lamp is provided to show when the circuit is broken and to light the switch to indicate the need to repair the fuse when the fuse is burned down due to overload of the circuits. To change the fuse, one merely pushes a drive link so that a pawl of the link drives the rachet wheel, and thus the radiating fuse to rotate another pair of fuse radiating arms into position thereby continuing the power supply. At the same time, the indication lamp is shut off.

Abstract: A fused plug has a fuse cavity containing active and spare fuses which can be alternated between active and inactive positions. The fuses in turn preferably each have multiple fuse elements which can be alternatively placed in active position by changing the position of the fuse in the fuse cavity.

Abstract: A selector fuse to be used in an ordinary fuse socket, having a cup-shape body with an exterior screw threaded sheath thereon. A plurality of (3) contact fuse members in the interior are connected with the sheath. A rotatable shaft has a contact finger engaging the fuse members successively upon rotation of the shaft. The fuse members are spring biased radially inwardly, and yieldingly maintain engagement with the finger, and have detent formations yieldingly holding the shaft in set position. Additionally, the fuse members are so shaped as to block reverse rotation of the shaft. The fuse members may be of different, or the same, fusing values, as desired.
