The mobile contacts can be moved within their support, determining the order in which contact is established. The multi-polar switch includes several contacts (11a,b,c,d) mounted on a contact support (13) facing a further set of contacts (12a,b,c,d). The first set of contacts are mobile and are mounted on a rotating support (13), whilst the second set of contacts are mounted on a fixed plate. Some of the contacts mounted on the rotating support are movable w.r.t. their mounting in this support, such that they may be moved into a position where they make contact with their respective opposite contacts more or less quickly than their neighbours. These contacts are held in position within the rotating support (13), urging them against an upper internal surface. |
