The invention belongs to the technical field of airplane cabin door structural design, and particularly relates to a large cabin door motion state indicating device. Comprising a connecting shaft, a first cam, a second cam and a pull rod are arranged on the connecting shaft, and the pull rod is connected with a cabin door; the terminal switch module for indicating the opening state of the cabin door comprises a first terminal switch, a first switch pressing block mechanism and a first support. The terminal switch module for indicating the closed state of the cabin door comprises a second terminal switch, a second switch pressing block mechanism, a second reset spring and a second support. According to the large cabin door motion state indicating device, one set of mechanism and two electric switches are used, three kinds of electric signal combinations are output, and accurate indication of the cabin door motion state and coordinated linkage with other cabin doors can be achieved; compensation measures are adopted in the design, and the problem that structure deformation and vibration in airflow moving at a high speed easily cause false indication of the electric switch is solved.
