Life Test
Life Depends Mostly On:
▪ Material Hardness: 50 Shore A is preferred.
▪ Low Stroke: less than 1mm.
▪ Angle (As illustrated in A): 40° is recommended.
▪ Length of sidewall (As illustrated in B): longer is better.
▪ Thickness of sidewall (As illustrated in C): determined by key structure, thicker will have longer life.
