Hi Vinny , thanks for your reply, the DTI's I used did have flat plastic backs on them as standard, I am not sure how thick as I have not taken one off but the plastic seemed to have no effect at stopping the magnetic field because with out my added steel sheet the magnet just stopped the plunger returning at all 
Hope you have better luck but I would try with just holding things together before spending too much time making anything properly jsut to prove the concept................ saying that , thats what I did and the bugger worked until I tried it again
Cheers Mick.
