Switching device

The invention relates to the low-voltage electrical field, in particular to a switching device, which is characterized in that one end of a movable contact element is rotatably arranged on a mounting structure through a first guide structure, the other end of the movable contact element is matched with a static contact element, and two ends of a swing stroke of an operating element are respectively matched with a positioning structure in a limiting manner; the second hinge structure connected with the other end of the second transmission structure is matched with the second guide structure of the movable contact piece and arranged on the second guide structure of the movable contact piece in a sliding mode, and the supporting structure is matched with the actuating structure in a hasp mode. The first hinge structure is slidably arranged on a supporting structure guide structure of the supporting structure; in the closing or opening process of the movable contact piece and the static contact piece, the first g
