ABSTRACT:
A contactor comprises first and second armatures which are urged towards contact-making positions by first and second windings, respectively. Each of the armatures displaces the other armature from its contact-making position when moving towards its own contact-making position. A controller actuates each of the windings before deactuating the other of the windings.
