とする開閉器。In a switch equipped with a spring device that drives a movable contact and separates the movable contact from a fixed contact by releasing a latch rotatably supported by an operation handle, the spring device is suddenly released. The movable contactor is composed of a spring having a special characteristic and a spring having a slow characteristic, and from the joined state of the movable contactor and the fixed contactor until they start to separate, the movable contactor is moved by the combined force of both springs. and the movable contact is driven only by the spring having the slow characteristic until the movable contact starts to separate from the fixed contact and completes the subsequent separation.
