Abstract
A switch includes a blade-type moving contact that extends in a radial direction from a turning center and reciprocates such that its free end draws a turning locus, and a fixed contact that moves toward and away from the moving contact in a turning range of the moving contact. The blade-type moving contact and the fixed contact are accommodated a tank. The moving contact is supported by the movable-side support conductor. The fixed contact is supported by the fixed-side support conductor. An opening through which the moving contact enters is arranged to be opposed to a turning center of the moving contact. The movable-side support conductor and the fixed-side support conductor are arranged substantially on a same straight line extending along a center axis of the tank.
Claims18
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;
- and
- wherein the free end of the moving contact has a shape extending along the turning locus of the moving contact;
- and
- 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 the movable-side support conductor and the fixed-side support conductor are arranged substantially on a same straight line extending along a tank center axis.
