Disconnecting switch contact

The invention discloses a disconnecting switch contact which comprises a fixed contact assembly and a moving contact assembly matched with the fixed contact assembly. The fixed contact assembly comprises a first conductive tube, fixed contact fingers, memory alloy tension springs and a finger base. The first conductive tube is connected with the finger base. The paired fixed contact fingers are installed on the two sides of the finger base oppositely. The memory alloy tension springs are connected between the paired fixed contact fingers. The moving contact assembly comprises a second conductive tube and a moving contact body. The moving contact body is connected with the second conductive tube. The nickel-titanium shape memory alloy tension springs are adopted to replace existing common spring steel plates, the problem that a disconnecting switch loses efficacy due to overheating of springs is solved fundamentally, and therefore the frequency of disconnecting switch heating accidents and large-area power outage accidents is greatly reduced, a large number of manpower and material resources for overhauling and maintaining are saved for the electric power department, and urgent needs of domestic power operation enterprises are met.
