The copper rider has silver coated areas for making contact with the bar, and with external connections. The bar consists of an aluminium profile with copper contact riders fitted in intimate contact with the aluminium at the ends, and at regular intervals. The sides of the riders (20) have on their internal surfaces silvered panels (A) which may be in the form of bands (24) which run transversely w.r.t. the length of the bar. On their outer faces, the riders have further silvered panels (B), situated between the two inward facing panels. The internal silvered panels are used in soldering the rider to the profile, whilst the external panels are used for the connection of external contacts. |
