Patent ID: 8432067

Claim:
An external electrical power adaptor apparatus, comprising, a power-accessing plug able to electrically connect to an external source of electrical power; a power supply circuit comprising circuitry to convert the external electrical source power into an electrical form useful for consumption by an electrical device; a first connector that is electrically connected to the plug and the power supply circuit, the first connector, comprising, a mechanical switch (1) having an opened position when the apparatus is not electrically and physically attached to an electrically powered device where the open switch prevents the consumption of any and all electrical power by the power adapter apparatus when the plug is electrically connected to the source of electrical power and (2) having an automatically closed position when the apparatus is electrically and physically attached to the electrical device whereby current is able to flow through the apparatus; and a second connector comprising a first end electrically attached to the power supply circuit and a second end removeably, electrically, and physically attachable to the electrically powered device so as to be able to convey power to the attached device.
