<p>A conductive bar structure suitable for connection to electrical switches or other modular electrical apparatus has two or more electrically conductive strips (1) housed in an elongate insulating casing (3) having an opening along one side which is closable by a removable cover (5) in which are formed a plurality of longitudinal slots (6) the length of which is parallel to the length of the casing. Within the casing (3) there are a plurality of longitudinally extending insulating partitions (10) defining guide channels (2) in which the bars (1) are housed so as to be separated and insulated from one another. Each bar (1) has a plurality of lateral projections (7) lying in a plane parallel to but offset from the general plane of the bar (1) itself, the degree of offset being determined by the channel in which the bar (1) is intended to be fitted so that the projections can extend through the slots in the cover. Unwanted projections can be removed at a convenient weakened line at the root of the projection.</p> |
