Abstract
A switch includes a fixed contact, a movable contact, a motor to drive the movable contact via a drive mechanism that converts rotational motion into linear motion, and a drive controller to control driving of the motor. The drive controller controls a rotation speed of the motor such that during an opening operation of the switch, a moving speed of the movable contact in a part of an entire moving range of the movable contact is lower than a moving speed of the movable contact during a closing operation of the switch. The part of the entire moving range includes an interrupting point at which an arc current is extinguished.
