    Abstract: An apparatus for electrically connecting a power source to an electrical device is disclosed. The apparatus comprises a first component and a second component. The first component has a substantially planar contoured first face comprising a ferromagnetic plate, a first set of contacts electrically connectable to a power source, two power switches and a magnetically actuated sensor controlling the switches. The second component has a substantially planar contoured second face complementary to the first face comprising a magnet and a second set of electrically conductive contacts electrically connectable to a device. Connecting the first and second faces, results in the first and second pair of contacts electrically coupling and establishes an electrical path between the power source and the device, and connects the components by magnetic attractive force which actuates the power switches and initiates power to the device. The apparatus further comprises a safety circuit for preventing electric shock.
