A self-centering, push-pull cable apparatus for automatically returning a controllable mechanism from an actuated position to a neutral, centered position. The cable apparatus includes a push-pull cable having an outer housing element and an inner movable core element and a two-way spring device operatively connected at one end to the outer sheath and at its other end to the core element. The spring device is oriented in axial alignment with the longitudinal axis of the cable apparatus and applies a force in both axial directions. This permits automatic return of the core element to a centered position when the input load is relaxed.
