Abstract
The position sensor senses the position of a movable finger in relation to a cooperating finger. The position sensor includes a variable reactance device including two cooperating relatively movable reactance elements. One of the reactance elements is mechanically coupled to the movable finger and the other one of the reactance elements is mechanically coupled to a cooperating finger. The relative movement between the reactance elements is effective to vary the reactance of the variable reactance device. An oscillator circuit is connected with the variable reactance device so that the frequency of the oscillator circuit varies to provide a variable frequency output which represents the position of the movable finger with respect to the cooperating finger.
