To provide a movable contact capable of reducing wear of a fixed contact or a resistor.

A first movable contact 100 is a ring-like metal plate capable of rotating on a first fixed contact 300. The first movable contact 100 includes: a base 110; first, second arms 120a, 120b consecutively connected to a fastening part 112 of the base 110; and first, second slide parts 130a, 130b consecutively connected to the tip parts of the first, second arms 120a, 120b. The first, second slide parts 130a, 130b are arranged so as to slide on the first fixed contact 300 on mutually different slide orbits according to rotation of the first movable contact 100.
