ABSTRACT:
A contractor (1) having at least two spaced-apart fixed contacts (2, 3) and an at least sectionwise electrically conductive, movable contact bridge (9) having at least two contact points (8) which are associated with the fixed contacts (2, 3). The contact bridge is adapted to be moved to a switched position by a switching force (B) and to a rest position by an opening force (V). The opening force (V) is produced by a pretensioning device (13). A particularly advantageous distribution of the opening force to the two contact points and a reliable switching operation is achieved in that one contact (2) is arranged between the other contact (3) and a point where the opening force (V) acts on the contact bridge (9).
