Abstract:
1. A vacuum switch tube, comprising: a first conductive rod and a second conductive rod, wherein a first contact is disposed at an end of the first conductive rod, a second contact is disposed at an end of the second conductive rod, and the first contact and the second contact are sealed in a vacuum tube body and disposed facing each other; a front end of the first contact is a convex hemisphere, the second contact is an annular body matching with a shape of the convex hemisphere, and the first contact comprises a first conductive member and a first magnetic member, the first conductive member and the first magnetic member extend in the same direction and match with each other in adjacent, the cross section shape of the first magnetic members is divided by a neutrality line into two unequal regions; the second contact comprises a second conductive member and a second magnetic member, and the second conductive member and the second magnetic member are partitioned by a midline of the second contact; the first magnetic member of the first contact and the second conductive member of the second contact are correspondingly disposed, and the second magnetic member of the second contact and the first conductive member of the first contact are correspondingly disposed.
