ABSTRACT:
A rotary direction detecting sensor for use on an automobile includes a pair of switching means provided radially from an axis of a steering shaft, and angularly spaced from each other at a predetermined angle about the axis. A first rotary member and a second rotary member are provided around the steering shaft, one of the rotary members being rotated in accordance with the rotation of the shaft and the other of them being limited in rotation to a substantially half angle of the angle between the switching means. In response to one direction of the rotation of the shaft, one of the switching means is selected to actuate blinking of one turn indicator lamp whereas the other of the switching means is held at its original deactivated position. On the other hand, in response to the other direction of the rotation of the shaft, the other of the switching means is selected for its operation.
