Patent ID: 8747135

Claim:
A method for the selection of power from two or more different circuits, said method comprising the steps of: providing a chassis with an electrical chassis receptacle for providing power from said two or more different circuits that are electrically connectable to said chassis for the supply of said power thereto; providing a duplex element having at least one electrical duplex receptacle, said duplex element additionally having first conductor means therein for electrical connection to said chassis receptacle, said duplex element being connectable to said chassis in different orientations for selection of power from one of said two or more different circuits; providing said chassis with a plate member for engaging said duplex element, said plate member being slidably movable in relation to said chassis for alternately moving said duplex receptacle into and out of electrical contact with said electrical chassis receptacle; choosing one of said two or more different circuits to which to electrically connect to said at least one duplex receptacle by choosing an orientation in which said duplex element is to engage said chassis; and engaging said duplex element with said plate member in said orientation and sliding said plate member and duplex element towards said electrical chassis receptacle to electrically couple said at least one electrical duplex element with said electrical chassis receptacle, thereby electrically connecting said at least one electrical duplex receptacle with said chosen one of said two or more different circuits.
