Abstract
A circuit assembly and package incorporates a front cover with power contacting blades extending from a front surface thereof for electrical engagement in a receptacle having a standard peripheral dimension. A housing is attached to the front cover and extends perpendicularly therefrom. The housing contains an electrical circuit connected to the power contacting blades which is contained on a plurality of circuit boards mounted substantially perpendicular to the front cover. The housing and front cover create a footprint less than the peripheral dimension of the receptacle. A connecting cable extends from the housing and is connected to the electrical circuit.
