Abstract
The utility model discloses an isolating switch and a static contact component of the isolating switch. The isolating switch comprises a static contact frame; a static contact is arranged at the lower part of the static contact frame and is rotatably matched with the static contact frame through a rotating shaft; the rotating shaft is insulated from the static contact; a one-way limit structure for limiting the swinging angle of the static contact is arranged in the corresponding position of the static contact on the static contact frame after finishing switching on the isolating switch; the center line of the inserting end of the static contact, which is extended along the splicing direction, is defined as the center line of the static contact; a plane which passes through the center line of the static contact and is parallel to the axis of the rotating shaft is defined as a central plane; and the one-way limit structures on the rotating shaft and the static contact frame are separately arranged at two sides of the central plane. The isolating switch is tilted by making use of the gravity of the static contact in the static contact component. When the isolating switch is closed, the inserting angle of the movable contact at the terminal of a main knife switch is corresponding to the tilting angle of the static contact; therefore, the static contact realizes automatic centering in the process of switching on so as to finish switching on.
