Abstract
The invention relates to a power grid accessory, in particular to a cord switch. The cord switch can conveniently enable a wire inlet binding post and a control part to be disconnected through a control mechanism, the control part is not energized, namely a pull rod is not energized when an insulating stay wire is replaced, and the insulating stay wire is very convenient to replace. In addition, the length of a control rod is equal to a distance from the inner side of the top wall of a cover screwed on a base to the upper end of a slide block, and actions of an operation rod is controlled by utilizing the cover during operation. An linage function exists between the operation rod and the cover, namely the operation rod cannot enable left and right contacts to be closed for a long period of time after the cover is opened and automatically enables the control part to be de-energized under the effect of a reset spring when the cover is opened, the cord switch is safe during overhauling, meanwhile can prevent operators from forgetting to close the cover after the insulating stay wire is replaced, and is safe in use.
