Abstract:
A breaker 1 comprises: a first terminal piece 2 on which a fixed contact 21 is formed; a movable piece 4 having a movable contact 41, in which the movable contact 41 is pressed to contact the fixed contact 21; a thermally reactive element 5 that deforms in association with a temperature change, thereby operating the movable piece 4 so that the movable contact 41 separates from the fixed contact 21; and a second terminal piece 3 electrically connected to the movable piece 4. The movable contact 41 includes a first movable contact 41a arranged at a first longitudinal-direction end part 40a of the movable piece 4, and a second movable contact 41b arranged at a second longitudinal-direction end part 40b of the movable piece 4.
