<p>Electrical apparatus, in particular a luminaire, having a working part (2) (luminaire head) arranged pivotably and rotatably on a holder (1). Both the mechanical and the electrical connection of the two parts are performed via a ball-and-socket joint, the ball of the joint being mounted in the housing (4) of the working part (2) of plastic, and simultaneously co-operating with electrical contact elements (7, 8). The part (3) of the joint which carries the ball is provided along its longitudinal axis (A) with a bore (5), the wall of this part (3) forming one phase of the electrical conductor, and the other phase extending, electrically insulated with respect to the wall, in the bore (5). <IMAGE></p> |
