Abstract
An indicating fuse is provided with an indicator at the free end of a movable spring contact, the indicator being located at an angle with respect to the plane of the spring contact. Provision is made for lower rated fusing currents utilizing the same basic fuse structure by forming a slot in the flexible spring contact at the point of maximum bending. A rounded shoulder is formed on the fuse carrier body across which the spring contact member is bent to minimize breakage and damage. The flexible spring contact is integrally formed with a U-shaped terminal that mounts it on the fuse carrier body, a second substantially identical generally U-shaped terminal also being secured to the fuse carrier body to provide a fixed contact. Molded ribs are formed in the insulating material of the fuse carrier body adjacent the open ends of the U-shaped terminal members to prevent the terminals from pinching together to form an undesired tapered configuration.
