Device for determining an interruption in an electrical, a a plurality of exchangeably disposed in sockets connected in series with lamps, for example, socket, which receives the circuit

摘要

A device for locating an open circuit in a string of Christmas tree lights connected in a series. The device comprises a pliers-like apparatus having opposed movable jaws to releasably grasp a pair of conductors 12, 14 leading to a socket in a series connected string of Christmas tree lights. The pliers are made from a non-conducting material and at least one set of jaws includes a plurality of conductively connected prongs 22 to penetrate the insulated covering of the conductors causing the socket to be short circuited. The pliers include a device (recesses 30, 32) for aligning the conductors with the prongs whereby closing of the opposed jaws causes the prongs to penetrate the insulation and short circuit the socket causing the string of lights to light when an open circuit is shorted.
