Abstract: There is disclosed an electric plug including a body member to which switches and two electrically conductive legs are mounted, in which an electric cable including at two electric wires is connectable to the body member, and the legs are electrically connectable to a source of electricity, in which one of the electrically conductive legs is electrically conectable in series with one of the elelctric wires via a fuse which is releasably attachable to and movable with the switches, and the switches are operable to move the fuse between a position in which the fuse is in electrical connection with the leg, and a position in which the fuse is out of electrical connection with the leg.
