    摘要: The keys (12) of the keyboard of an electronic instrument interact with A-shaped action arms (26) pivoted adjacent the apex, and weighted (36) at the cross bar. The free ends of the limbs (48, 50) of each action arm engage above and below the rail of the associated key. An actuator (46) on each action arm operates an electric sensor in the form of a break-before-make switch (34).
