Abstract
A capacitive position sensor for sensing changes in the position of a rotating element, in which there are two sets of stationary capacitive surfaces, one set forming a first integral unit, the other set forming a second integral unit; the two units are held together with the surfaces of each set resting in corresponding spaces in the other unit such that all surfaces of both sets intersect a common radial plane and the surfaces of one set are electrically isolated from the surfaces of the other set.
