Abstract:
1. An operator interface assembly for a machine, comprising: a base, an operator input device operable to move in a first direction in relation to the base to a second position and a third position and in a second direction in relation to the base to a fourth position, a first biasing member including a first spring end, and operatively associated with the base and wherein the first spring end is operable to contact the operator input device at a first position and resist movement of the operator input device in the first direction from the first position to the second position, a second biasing member including a second spring end, and operatively associated with the base and wherein the second spring end is operable to contact the operator input device at the second position, the second position different than the first position, and resist movement of the operator input device in the first direction, wherein the second biasing member is operable to resist movement of the operator input device in the second direction from the first position to the fourth position, and the first biasing member is not operable to resist movement of the operator input device in the second direction from the first position to the fourth position, and a position sensor configured to generate a position signal for generating a machine control command, the position signal indicative of the operator input device position.
