ABSTRACT:
An actuating mechanism having three detented actuating positions. The actuating mechanism includes an arm having a roller rotatably mounted thereon. The roller bears against the sides of two juxtaposed coil springs which bias the arm into a neutral position when the roller is received between the springs, and an actuated position on either side of neutral when the roller rides past the centerline of one or the other of the springs. In accordance with one aspect of the invention, directional switches are actuated by the arm when the arm is moved to either side of neutral.
