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.
