- The trigger switch mechanisms of nutrunners are important for operators to perceive feedback while tightening bolt joints. Previous studies focus on associations between discomfort evaluations and powered tool operation. This paper addresses how operator preferences are linked with functionality requirements from trigger switch mechanisms. Subjects evaluated five switch mechanism prototypes regarding perceptions of quality, feedback, firmness, and distinctness. Results suggest that loading and unloading phases of trigger operation are significant predictors of perceptions of quality. The trigger switch mechanism with a combination of high peak-drop-bottom forces was perceived with better quality, feedback, and distinctness in comparison to the other mechanisms. The study also revealed that when the switch mechanism was designed to give more distinctness and feedback, higher quality is perceived.
