Abstract
Damping apparatus within an actuator device in which a backstop is supported on one portion of a dual cantilever to match the movement of the impacting actuator to reduce wear and provide positive restoration of initial position, wherein the backstop-supporting cantilever portion is embedded in energy-absorbing elastomeric material that is symmetrically confined to shorten settling time of the actuator and remain unaffected by temperature changes.
