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.
Claims3
A switching system comprising in combination, a contactor and a controller for the contactor, the contactor comprising first and second armatures, each of which has a respective contact-making position, and first and second windings for urging said first and second armatures, respectively, towards said respective contact-making positions, each one of said first and second armatures being operable to displace the other of the first and second armatures away from its respective contact-making position when said each one of said first and second armatures is urged by a respective one of said first and second windings to its respective contact-making position, and, the controller comprising first and second output stages for driving said first and second windings respectively, and a switch over circuit for actuating each of said first and second output stages before de-actuating each other of said first and second output stages.
