<P>PROBLEM TO BE SOLVED: To provide a contact device that suppresses the upsizing of the device and obtains larger contact pressure. <P>SOLUTION: The contact device includes: fixed terminals 33 having fixed contact points 32; a movable contact 35 having movable contact points 34 that are made to contact and separate from the fixed contact points 32 on the top surface and an insertion hole 35b formed therethrough; a yoke plate 6 that is disposed on a top surface side of the movable contact 35 and has an insertion hole 6a formed therethrough; a yoke plate 7 that is disposed on a lower surface side of the movable contact 35, has an insertion hole 7a formed therethrough, and faces the yoke plate 6 across the movable contact 35; a contact pressure spring 36 that energizes the movable contact 35 toward the fixed contact points 32; a contact part 52 that regulates the movement of the movable contact 35 toward the fixed contact points 32; an axis part 51 that is connected to the contact part 52 and is composed of a magnetic material freely movably inserted into the insertion holes 6a, 35b, 7c; and an electromagnet block 2 for driving the axis part 51 such that the movable contact points 34 are made to contact and separate from fixed contact points 32. <P>COPYRIGHT: (C)2012,JPO&INPIT |
