Magnetic fixing for electrified rail (3), particularly for the electrification of metal shelving (1) units provided on their front of electronic labels, displays and/or other peripheral devices, said rail comprising a body of electrically insulating plastic material, provided with longitudinal slots suitably distanced to each other, in every one of which metal conductor (8) can be reached by an electric contact useful to connect the same conductor to a plug or an electric or electronic device, fixed to said body of the rail,
characterized in that
for fixing said rail to said metal shelving (3) two kinds of magnets (5, 6) are present, having distinct magnetic force, one (5) weaker, e.g. lower than 1 N/cm 2 and one (6) stronger, e.g. in the order of at least 10 N/cm 2 . |
