Abstract
Embodiments provide a switch, including a control system, first and second manipulating mechanisms. The control system emits an operating instruction to the second manipulating mechanism when the wire works normally, the operating instruction instructing the second manipulating mechanism to perform an opening action or a closing action; the control system emits a first and second action instructions to the first and second manipulating mechanisms, respectively, when the wire fails, the first action instruction instructing the first manipulating mechanism to perform a first action, and the second action instruction instructing the second manipulating mechanism to perform a second action, the cooperative action between the first manipulating mechanism and the second manipulating mechanism implements redundancy of the switch operating; and the time taken by the first manipulating mechanism to implement the first action is different from the time taken by the second manipulating mechanism to implement the second action.
