The invention relates to an interlocking device for a switch device and a switch cabinet using the same. The interlocking device for the switch device comprises a connecting rod, a stander plate and a rotating wheel fixedly connected with a two-workstation mechanism gear, wherein the rotating wheel is provided with a cam contour groove, the cam contour groove is connected with one end of the connecting rod in a sliding manner, the other end of the connecting rod is hinged with a limiting device for limiting a half-shaft crank arm fixedly connected with a circuit breaker closing half shaft, and the limiting device is connected with the stander plate in a sliding manner and is driven by the connecting rod to make reciprocating linear movement on the stander plate; the cam contour groove comprises a first groove section, a second groove section and a third groove section, and two ends of the first groove section are connected with the second and third groove sections; when the connection end of the connecting rod and the cam contour groove stays on the first groove section, the limiting device stays on a first position in the linear movement direction; and when the connection end of the connecting rod and the cam contour groove stays on the second and third groove sections, the limiting device stays on second and third positions in the linear movement direction, so that the problem that the two-workstation mechanism cannot be interlocked with a longitudinally arranged circuit breaker can be solved.
