1. An electronic accessory for a shade structure, the electronic accessory comprising:a power supply unit configured to be suspended beneath a component of the shade structure, the power supply unit comprising a housing having a lower surface with a recess disposed therein; and
a functional unit that utilizes electrical power from the power supply unit to perform a function, the functional unit comprising an upper surface and a power transfer support extending away from the upper surface, the power transfer support comprising a central body and at least two projections extending laterally from the central body, the at least two projections each comprising an electrical contact,
wherein the recess of the lower surface of the power supply unit housing comprises at least two laterally extending regions, each of the laterally extending regions corresponding to one of the at least two projections, each laterally extending region being adjacent a support surface disposed within the housing,
the projections and laterally extending regions being arranged such that insertion of the projections into the laterally extending regions and relative rotation of the functional unit with respect to the power supply unit positions the projections to be supported by the support surfaces over the support surfaces and engages the electrical contacts of the projections with corresponding electrical contacts disposed within the housing of the power supply unit.
