Abstract:
A contact device includes a fixed contact, a movable contact, a housing, and an arc extinguishing member. The movable contact moves between a closed position where the movable contact contacts the fixed contact and an open position where the movable contact is separate from fixed contact. The housing houses the fixed contact and the movable contact. The arc extinguishing member is disposed in the housing and discharges an arc extinguishing gas. The arc extinguishing member is disposed facing a gap between the fixed contact and the movable contact when the movable contact is in the open position. The arc extinguishing member has a shape that tapers toward the gap.
