ABSTRACT:
A control has a pivotal part with an operating surface that can be depressed by a person's foot or hand, with pivoting being sensed by a pivot sensor. A spring-operated mechanism urges the pivotal part toward an initial position while allowing it to pivot in both clockwise and counterclockwise directions from the initial position, the sensor indicating the amount of pivoting in either direction from the initial position. A damping unit for limiting the speed of depression includes a cylinder that contains fluid and a plunger that is depressed by the pivotal part into the cylinder to displace the fluid.
