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: A contact apparatus is provided and includes fixed terminals having fixed contacts, a movable contact member having the movable contacts provided on one surface thereof so as to come into contact or out of contact with the fixed contacts, a first yoke arranged at one side of said one surface of the movable contact member, and a second yoke arranged at a side of the other surface of the movable contact member, the second yoke having one surface facing the first yoke through the movable contact member. The first yoke is larger in volume than the second yoke.

Abstract translation: 接触装置包括：接触块，其包括形成有固定接触件的多个固定端子;以及活动接触器，活动触头接触和离开固定触点; 以及驱动活动接触器的驱动块。 此外，通过在接触块的周边配置永久磁铁，可以消除在触点接触和离开的情况下产生的电弧。 然后，多个固定端子中的至少一个固定端子被形成为使得固定触点和可动触头可以在与另一个固定端子相对的一侧以外的区域中彼此抵接。
