Abstract
Abstract An improvement is provided in a combination flashlight (or lantern)/continuity tester having an insulated body and a (flashlight) bulb and batteries in series circuit. The improved tester, which is formed in the flashlight (or lantern) body, includes an entry site of a particular configuration into the interior of the body. The testing means includes a pair of electrically-conductive strips, each strip having a contact portion, adjacent to the body entry site and penetrating into the interior of the body. Each strip is also in electrical contact with the series circuit. The shape of the entry site is such as to guide terminals of the circuit element being tested into contact with respective ones of the strips. The electrical continuity of a fuse or light bulb is determined by the lighting of the bulb being tested and/or by the lighting of the lamp bulb of the flashlight.
