The storage degradation test system for aerospace relay is designed. The degradation data rule of pick-up time parameters for aerospace relay is tested. And the variation law of pick-up time changing with time is obtained. The change of pickup time which is mainly caused by reeds reaction occurred relaxation, is analyzed and verified. Then, the approximate linear relationship between pick-up time and reed reaction was found. So, the pick-up time can characterize the degradation of reed
