Try to re-write your problem a little clearer. Are you trying to replace a light? Is there more than one light switched on with this switch? Do the blue and brown wires in your 'new one' go to a hanging pendant? Or is this a different type of fitting, i.e. for decorative purposes? Some of us may be anle to shine a little light on your problem after that! If all else fails get a reputable electrician in your area to fit it for you as I do encounter some 'different' ways to fit lights from time to time! Good Luck
