Abstract: Electrical and physical mounting assemblies. The mounting assemblies include a male structure, a female structure, a retention structure, and a rotation control structure. The male structure has an outer surface and includes at least a first electrical contact that defines a portion of the outer surface. The female structure defines a receptacle that is sized to receive the male structure. The receptacle and the male structure are shaped to permit relative rotation therebetween about a rotational axis when the male structure is received within the receptacle. The female structure includes a second electrical contact that defines a portion of the receptacle. The first electrical contact and the second electrical contact are shaped to maintain electrical communication therebetween during the relative rotation. The retention structure is configured to selectively retain the male structure within the receptacle. The rotation control structure is configured to selectively restrict the relative rotation.
