Abstract: A contact device includes: fixed terminals; a movable contact maker; a pressing spring; an adjustment plate that comes into contact with an upper face of the movable contact maker; a holding portion; a movable shaft; and an electromagnet block. The holding portion is divided into first and second holding portions that are separated from each other. The first and second holding portions are electrically connected to each other via only the adjustment plate, due to the adjustment plate being sandwiched by a first side plate of the first holding portion and a second side plate of the second holding portion. The adjustment plate is moved in extending and contracting directions of the pressing spring, and the adjustment plate and each of the first and second side plates are subjected to resistance welding at a position at which pressing force of the pressing spring is a predetermined value.

Abstract: A contact device includes: a contact block including a plurality of fixed terminals on which fixed contacts are formed, and a movable contactor on which movable contacts contacting and leaving the fixed contacts are formed; and a driving block that drives the movable contactor. Moreover, it is made possible to extinguish arcs, which are generated in an event where the contacts contact and leave each other, by arranging permanent magnets on a periphery of the contact block. Then, at least one fixed terminal among the plurality of fixed terminals is formed so that the fixed contact and the movable contact can abut against each other in a region other than a side opposite to the other fixed terminal.

Abstract: An electromagnet device is configured to generate a magnetic attractive force between a stationary core and a movable core when electricity is applied to a coil, so that the movable core is moved in a direction for coming into contact with the stationary core, and a movable shaft is moved in a direction in which a first end face of the movable shaft separates from a movable terminal. After the movable contact comes in contact with the fixed contact, the movable core moves further in a direction for coming into contact with the stationary core. A yoke made of a magnetic body is disposed between the movable terminal and the first end of the movable shaft.
