Sealed contact device

摘要

The invention provides a sealed contact device capable of extinguishing an arc which extends in an arbitrary direction. The sealed contact device includes a housing; a fixed contact and a movable contact disposed in the housing in such a manner as to face each other; and permanent magnets which are disposed with the fixed contact and the movable contact interposed therebetween and which attracts an arc between the fixed contact and the movable contact using a magnetic force. An arc shielding member is disposed at a position to which the arc is attracted by current flowing between the fixed contact and the movable contact and by the magnetic force between the permanent magnets, in the housing.
