Abstract: An electrical circuit continuity tester is described having a minimum number of components and including only a bulb, a cylindrical tube, batteries, a spring and 2 contacts which also serve as probes. One contact grips the bulb, affording mechanical and electrical contact between it and the battery while it simultaneously retains all the components in relative position. The other contact is needle shaped and is designed to minimize possible inadvertent shorts. For assurance against the continuity tester disassembling in storage or use, a simple bulb cover locks the bulb gripping contact, and hence the entire assembly, in position.

Abstract: A cord conductor of two insulated conductor strands has a female terminal molded at one end and a conventional plug at the other. The female terminal has a pair of female contacts positioned therein which are in permanent electrical connection with their associated conductor strands. The female terminal is provided with a pair of terminal openings therein, the openings being adapted to frictionally receive the prong from a duplex plug that is in electrical connection with an electrical appliance. When the prongs are frictionally positioned in the terminal openings they are in slidable engagement with the female contacts to complete a portion of an electrical circuit.The pair of terminal openings has a safety closure associated therewith. The safety closure is mounted between the terminal openings and is movable between a first and a second position.
