<P>PROBLEM TO BE SOLVED: To provide a contact device in which noise is reduced by suppressing vibration generated from a movable contactor when a current flows through the movable contactor. <P>SOLUTION: The contact device 2 includes: three or more fixed contacts 231, 232, and 233; and the movable contactor 25 movable between a first position in contact with the fixed contacts 231, 232, and 233 and a second position separated from the fixed contacts 231, 232, and 233. When the movable contactor 25 is located at the first position, the movable contactor 25 includes a plurality of branch passages by which the current between the fixed contacts 231, 232, and 233 are branched by connecting the fixed contacts 231, 232, and 233 with each other. The fixed contacts 231, 232, and 233 are disposed so that at least a part of an influence of the current is cancelled and connection polarities thereof are symmetrical. <P>COPYRIGHT: (C)2013,JPO&INPIT |
