LEMA Buzzer

[RunningBare]

I thought some of you might like to look at this I just drew up

LEMA buzzer, pictured below, its an extremely rough outline drawing, the idea being that as the lever is pulled down by the magnet it pushes the shield across the magnet thats doing the pulling.

Now we all know the outcome, the shield will be pulled so far weakening the flux reaching the lever, so eventually a balance is reached and it will remain in one position.

But, what happens if we introduce mechanical hysteresis to the shield so that at a given point it snaps across the magnet?, the type of mechanical hysteresis I'm thinking of is similar to those toy clickers we use to have, remember them, the metal was formed in such a way that when pressed to a certain point they clicked, as you released they clicked back to original position.
The mechanical setup is done in such a way as a small movement of the hammer produces a large movement of the shield.

We already know from Craigy's replication of the LEMA that the shield is easy to move in comparison to the force the magnets exert.
If I manage to get my hands on a linear bearing I'm going to try this.
Anyway, just an idea, knock yourselves out.

And I forgot to add, the arm must not be any magnetic material, only the soft iron tip.

grr, I keep forgetting details!

The hammer must never come in contact with the magtnets or shield, so some sort of stopper is needed, perhaps stop the hammer 1 mill or less from the shield, but never touch.

Hi,

I cannot find or see your drawing in the first mail above, where is it?

I can see a small icon only with a red X in its middle, no picture.  Of course I am logged in.
