The invention discloses a conductive band, and a conductive rod mechanism and an isolating switch using the conductive band. The conductive band comprises a band body which is composed of layers of substrates, wherein the substrates positioned at the inward concave side is thicker than the substrates positioned at the outward convex side. Thus, under the circumstance that the total thickness of the band body is kept unchanged, the total number of layers of substrates in the band body of the conductive band provided by the invention can be reduced accordingly when compared with equal-thickness substrates in the prior art, thereby the number of heat sources in the band body is reduced, the heat productivity of the whole band body is reduced accordingly, and the radiating effect is improved; in addition, since the thickened substrates are positioned at the inward concave side of the layers of substrates, the expansion and contraction amplitude of the substrates at the inward concave side during the swinging process of the conductive rod is small when compared with that of the substrates at the outward convex side, that is, though thickness of part of the substrates is increased, the thickened substrates cannot cause excessive impact on the swing of the conductive rod, and thus the conductive rod can swing normally.
