Abstract
A rotational direction sensor for a body such as a steering shaft of an automobile, which is rotatable from a preferred neutral position in either the clockwise or the anticlockwise rotational direction. When an actuating assembly is rotated in the clockwise rotational direction by more than a predetermined amount from the neutral position, a first switch is actuated so as to conduct a first electric current, while a second switch is not actuated, and when the actuating assembly is then returned to the neutral position in the anticlockwise rotational direction, the second switch is actuated to conduct a second electric current. An opposite switch actuation sequence occurs for initial anticlockwise and then clockwise rotation of the actuating assembly. A control circuit generates a first electric signal when it receives the first and then the second electric current as a pair and a second electric signal when it receives the second and then the first electric current as a pair.
