PROBLEM TO BE SOLVED: To provide a switch in which a distance between both of electrodes when a movable electrode is opened from a fixed electrode can be easily adjusted to be a set value. SOLUTION: On a rotating operation shaft 16 of an operation mechanism 15 for rotating a movable electrode 5, there is fixed a rotating range regulating lever 25 rotating together with the operation shaft 16, the movable electrode contacts with the rotating range regulating lever each when the movable electrode rotates to a closing position or to an opening position, and position regulating members 26, 27 are provided on a closing position side and an opening position side for regulating rotating ranges of the operation shaft. On a movable electrode 5 supporting conductor 8, there is fixed a stopper 30 for positioning the movable electrode at the opening position by contacting with the movable electrode when the rotating range regulating lever 25 contacts with the opening position side regulating member, in a position-adjustable state. On a part of the stopper 30 contacting with the movable electrode, there is fixed an elastic member 30c for absorbing a shock generated when the movable electrode bumps it.
