Claim:
A switch comprising a blade-type moving contact that extends in a radial direction of a turning center and reciprocates such that a free end of the blade-type moving contact draws a turning locus, and a fixed contact that comes into contact with and separates from the moving contact, the blade-type moving contact and the fixed contact being accommodated in a tank, wherein the moving contact is supported by a movable-side support conductor, the fixed contact is supported by a fixed-side support conductor, the fixed contact has an opening through which the moving contact enters, the opening being opposed to the turning center of the moving contact, and an angle formed between a tank center axis and the moving contact located in a fully open position accommodated in a slit conductor, and an angle formed between the tank center axis and the moving contact located in a fully closed position where the moving contact comes into contact with the fixed contact are substantially equal to each other.
