摘要： The contact apparatus includes a fixed contact, a movable contact, and an arc extinguishing member. The movable contact is movable between a closed position where the movable contact is in contact with the fixed contact and an open position where the movable contact is separate from the fixed contact. The arc extinguishing member is for discharging an arc extinguishing gas offering a capacity for extinguishment of an arc, into a space containing the fixed contact and the movable contact.
