a housing presenting an internal chamber;

a first shifter mounted for pivotal movement relative to said housing about a pivot axis, said first shifter including a first hub member located at least partially within said internal chamber and a first lever extending from the first hub member outwardly of the internal chamber;

a second shifter mounted for pivotal movement relative to said housing, said second shifter including a second hub member located at least partially within said internal chamber and a second lever extending from the second hub member outwardly of the internal chamber;

a mounting assembly located in said internal chamber and mounting at least said first shifter, said mounting assembly including a friction assembly for resisting pivoting movement of said first shifter relative to said housing; and

a spring mounted within said internal chamber and substantially enclosed by said first and second shifters and said housing, wherein said spring operatively connects said housing and said second shifter and applies a biasing force in a direction transverse to the second pivot axis for applying a pivoting force to said second shifter, said second shifter being pivotal between a primary position and an alternative position, and whereby said spring is operative to pivot said second shifter from the alternative position to the primary position in the absence of an external force.
