Zusammenfassung: | The invention provides a neutral position limit switch head design with part reduction and improved reliability. A limit switch operating head includes a shaft rotatable in clockwise and counter- clockwise directions, a cam member supported on the shaft and that is rotatable in the clockwise and counter-clockwise directions responsive to rotation of the shaft, and a follower actuated by the cam member responsive to rotation thereof, with the follower including a pivot pin, a lever portion pivotable about the pivot pin, and a rolling pin mounted to the lever portion and in contact with the cammember. An actuator member contacts the lever portion and translates linearly in a first direction or second direction responsive to pivoting thereof. The rolling pin moves along a profile of the cammember upon rotation of the cam member so as to cause the lever portion to pivot, with the actuator member linearly translating in the first direction or the second direction responsive to the pivoting of the lever portion.
