Abstract: The invention relates to an electrical system with at least one electric load unit (E) magnetically attached to a surface (F) being provided with path conductors (L). The load unit (E) comprises an electric load (G) being mounted on a socket (S). The socket (S) is provided with at least one magnet (M) and contacts (K) are arranged at the bottom side of the socket (S), through which contacts electrical energy supplied by a low-voltage source (SP) is fed to the load (G) via said path conductors (L). The contacts (K) are arranged such that the load (G) can be switched ON or OFF when the load unit (E) is displaced and/or turned. The load (G) may be as luminary.
