The screws should be snug but with the plastic hub not terribly tight. There should be no rotational play other than the tiny bit that might be allowed with the pin and depression. My ring deflects very little. If I had to take a guess I would say the distance between the contact plate and where it contacts the ring edge is in the order of less than 1mm. That height is determined by the plastic insulator and wave washer in the middle and the length of the 3 black insulator washers holding the contact plate onto the ring. If yours is too close you might try a couple of layers of copy paper under those points and see what happens.
With no metal hub, as Marston mentioned earlier the problem is more likely to be with the wire or possibly that fiber insulator under the end contact. Less likely would be the contact plate is loose or warped. Since it happens when you turn the wheel I would say check the wire first. Where it comes out thru the end of the steering box in the engine compartment is a very vulnerable spot. Heat and grease can cause the insulation on the wire to fail right at the small hole where it exits the box. Turning the wheel and twisting the wire could be just enough to make a bare spot touch the box.
