The present invention relates to a switch that generates an arc in a container during current interruption, such as a current limiter or an electromagnetic contactor. The switch according to the present invention has conductor portions 21a, 22a and 23a connected to the terminal portion 5, conductor portions 21c, 22c and 23c for fixing the fixed contact 3 and conductor portions 21a, 22a, 23a and 21c. And the fixed contacts 21, 22, and 23 are formed by the conductor portions 21b, 22b, and 23b connecting the, 22c, and 23c. Moreover, the position of the contact surface of the stationary contact 3 is arrange | positioned below the position of the terminal part 5, and the conductor part 21b is arrange | positioned at the rotation center 14 side rather than the position of the stationary contact 3. Further, the position of the conductor portion 21a is higher than the position of the contact surface of the contacts 2 and 3 when the contacts 2 and 3 are on, and the movable contact (when the contacts 2 and 3 are off). It should be lower than the position of the contact surface of 2). Moreover, the position of the conductor part 22a is set upwards than the position of the edge part where the contact 2 of the movable contact 1 is fixed, when the contact 2, 3 is in an on state, and the contacts 2, 3 are When it is in an off state, it is lower than the position of the contact surface of the movable contact 2. Moreover, the position of the conductor part 23a is set above the position of the edge part where the contact 2 of the movable contact 1 is fixed, when the contacts 2 and 3 are on, and the contacts 2 and 3 are off. In the state, it is lower than the position of the contact surface of the movable contact 2, and it is higher than the part 1b of the movable contact 1 of the rotation center 14 shaft from the movable contact 2. As shown in FIG. The above-described configuration provides a switch having excellent current-limiting performance and less damaging by arc energy and releasing hot gas to the outside.
