Abstract
Recently, a new added value in addition to a basic performance of a switch for automobile is expected. The purpose of this research is to pay attention to comfortable switch sound in consideration of tactile feeling. First, subjective evaluations of the tactile feeling of the switch and its operation sound are examined by semantic differential method. Then, the common specific factors between the tactile feeling and the operation sound are extracted by factor analysis. Moreover, the specific factors and physical properties such as the input force and its sound pressure level are analyzed to estimate the relationship between subjective evaluation and objective evaluation.
