TANGENTBORDSMEKANISM

摘要

A bounce dampening system reduces switch actuator bounce when the actuators are restored to their home position. Included are selection interposers, one of which is selectively driven to thereby effect motion of selection bails and corresponding switch actuators. A reverse interposer is simultaneously driven. A spring restores the reverse interposer after the actuation cycle thereby carrying the bails and switch actuators to their home position. The return spring and the mass of the reverse interposer prevents actuator bounce and insures a timely return of the actuators.
