A device for interconnecting electrical wiring or for accessing electrical current carried by electrical wiring includes an electrical junction housing for receiving an electrical cable, an inner housing inserted into the junction housing to connect the individual wires of the incoming electrical cable to a first magnetic electrical connector carried by the inner housing. A physical interface device such as a switch or a wall socket is then wired to a second magnetic electrical connector that can be plugged into the electrical junction housing. The two magnetic electrical connectors, when joined in the correct orientation, pass electrical current.
