<P>PROBLEM TO BE SOLVED: To provide a contact device capable of preventing reduction in contact pressure acting between contacts by efficiently negating electromagnetic repulsive force, and also to provide an electromagnetic switching device using the contact device. <P>SOLUTION: The contact device includes: respective fixed contacts 10A to 10C and respective movable contacts 12A to 12C which come into contact with and are separated from each other; a movable contactor 12 having the respective movable contacts 12A to 12C provided thereon; and a shaft 14 integrally interlocked with the movable contactor 12. On the shaft 14, an extension part 15 is provided which extends to the side opposite to the respective fixed contacts 10A to 10C side by penetrating through the movable contactor 12 from the tip, and at one end of the extension part 15, a flange part 16 is provided. Between the flange part 16 and the movable contactor 12, an auxiliary spring 17 is provided which energizes the movable contactor 12 in a direction facing to the respective fixed contacts 10A to 10C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
