Abstract
A rotational position indicator useful for example for indicating wind direction is provided by a stator having nine position sensors substantially equally spaced around the circumference of a circle and an armature mounted for rotation on an axis located at the center of the circle. The armature is formed with two position sensor actuators mounted at approximately 140.degree. relative to each other. Each position sensor actuator is mounted at a radial position for selectively actuating the position sensors upon rotation of the armature. An electric circuit is coupled to each position sensor for indicating actuation or not of the respective position sensor. The output provides a unique position code for successive intervals of angular positioning of the armature relative to the stator. The actuators have an actuating effect over a selected angular interval sufficient to produce 36 unique position codes for indentifying successive 10.degree. intervals of angular positioning of the armature relative to the stator.
