Claim Text:
1. A steering mechanism having an interface for converting rotational motion to electrical signals, the interface comprising: a shaft which is rotationally moveable in a first direction and in a second direction; a first and a second electrical component mounted on the shaft and arranged so that rotation of the shaft in the first direction causes changes in electrical properties of the first electrical component and rotation of the shaft in the second direction causes changes in electrical properties of the second electrical component; the first and the second electrical components being connected to one or more electrical circuits so that rotation of the shaft in the first and the second directions causes changes in the one or more electrical circuits; and the first and the second electrical components are free to rotate with respect to the shaft in a direction opposite to the direction of rotation causing a change in the electrical properties of the corresponding component.
