ABSTRACT:
An electrical plug is disclosed with a slidable earth pin that can be manually positioned in a stored position in a plug body of the electrical plug when the electrical plug is not in use. The slidable earth pin is movable in the channel and retained by an interlocking mechanism between the earth pin and the channel on the plug body. The earth pin has a pair of protruding fingers that snap into a first set of grooves in the channel of the plug body in a first position, and that snap into a second set of grooves in the channel of the plug body in a second or stored position. When the earth pin is in its stored position, the physical dimension of the plug is significantly more compact than conventional three pin plugs.
