Abstract (en)

The present invention relates to a moving contact protective sleeve, a contact module having same and an isolating switch. The moving contact protective sleeve comprises: a connecting body; a first protective plate, connected on one side of the connecting body; and a second protective plate, connected on another side of the connecting body; wherein the first protective plate, the connecting body and the second protective plate together form a cavity for accommodating a moving contact of the isolating switch. The moving contact protective sleeve according to the present invention is structurally simple and low-cost, can effectively protect the moving contact, and accelerate the extinguishing of an arc. It can enhance the reliability with which current is broken and established, and increase the safety and reliability of the entire contact module and the isolating switch.
