ABSTRACT:
Load and socket arrangements are disclosed wherein contacts within a socket are connected to an electrical energy source by a magnetic reed switch responsive to magnetic material carried by the load. The socket is disconnected from the source and incapable of producing electrical shock when the load is removed. In one embodiment, a lamp has a magnetic insulator separating its shell and base terminals. In another embodiment, a connector plug has a magnet carried within the body of the plug. Various sockets and circuits for connecting reed switches in the sockets are disclosed. Also disclosed are magnetic adapters for attachment to conventional lamps or plugs so that conventional loads may be used in the sockets.
