Abstract
A housing includes a first space, a second space, a first hole, a second hole, and an arc extinguishing member. A fixed contact and a movable contact are arranged in the first space. The second space is partitioned from the first space. The first hole communicates the first space and the second space. The second hole communicates the second space with a space outside the second space. The arc extinguishing member releases an arc extinguishing gas into the first space. The second hole has a smaller opening area than the first hole.
