  • Patent number: 5446388
    Abstract: A plier-type manual tool for removing and testing cartridge-type fuses is constructed of two pivoted elongated members providing jaw portions and handle portions. The handle portions are fabricated of rigid electrically insulative material. One of the handle portions is a testing handle and has an internal cavity which houses batteries and an indicator device such as a buzzer. Contact posts project from the interior surface of the testing handle in a spaced apart linear array along the length of the handle. Conductors within the handle join the batteries, the posts and buzzer in a partial series circuit. The series circuit is completed when a cartridge fuse having electrical continuity bridges two of the posts.
