In this research, to improve the operational feeling of the rotary switch, we investigated the construction method of the switch operation feeling model by grasping the correlation between the subjective evaluation and the physical quantity for the continuous complex stimulus of tactile sensation and operation sound. First, the impression was evaluated under a single stimulus of the tactile stimulus and the operation sound stimulus, and each physical quantity corresponding to each stimulus was
