Providing an electrical assembly, which can protect electric components provided at the electrical assembly from damage, and minimize output amount of recycle material and waste material, a functional module as the electric assembly includes a lamp and a switch as the electric components. The lamp extends from a center area of a bottom wall of a housing so as to slant toward an outside of the housing according to going apart from the bottom wall. The switch extends vertically from one end of the bottom wall. Ends of the lamp and the switch far from the bottom wall project out of the housing. When the functional modules are transported to an assembling line, the pair of functional modules is stacked on each other so as to arrange the lamp face to each other in parallel, and fixed to each other.
