Abstract
A switch includes a first fixed contact, a second fixed contact, a movable contact, a drive shaft, a first outside yoke, a second outside yoke, a first inside yoke, a second inside yoke, and a permanent magnet. The permanent magnet magnetically couples the first outside yoke, the second outside yoke, the first inside yoke, and the second inside yoke, and produces a magnetic field component in a direction in which the first fixed contact point and the second fixed contact point are aligned, between the first fixed contact point and the first movable contact point and between the second fixed contact point and the second movable contact point.
