The input member is rotatably mounted to the case, and is rotatable from an input member home position in each of a first rotational direction and a second rotational direction. The shuttle is movably mounted in the case, and is engaged with the input member such that rotation of the input member from the input member home position in each of the first rotational direction and the second rotational direction drives the shuttle from a shuttle home position to a shuttle actuated position. The output member is rotatably mounted to the case and engaged with the shuttle such that the output member rotates in an output member rotational direction in response to movement of the shuttle from the shuttle home position to the shuttle actuated position. ## Claims ### Claim 1 A rotation converter, comprising: a case;
