Contactor CJX2s mechanical interlock The reversible contactor group composed of two contactors has the characteristics of interval switching. In order to ensure its normal and safe operation, it is necessary to have a mechanical interlock function between the two contactors. At the same time, it can ensure that the two contactors will not be closed at the same time, but only after one of the contactors is disconnected, the other contactor can be closed, which can effectively prevent short-circui
