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 ).
