Air step mercury switches

[Don Bradner]

The light which indicates that my step is extended began staying on last week. A
bit of investigation shows that the part which should contact the mercury
switches has broken off. It is attached to the end of the air piston rod, and a
small piece of it remains on the other side.

I don't think it should be too hard to fabricate, but I don't know at all what
it looked like - flat piece of metal, z-pattern, or whatever.

After studying the air step wiring diagram until my eyes want to cross I think
it looks like, with neither switch working, I may be having continous power to
the step solenoid in both extended and retracted positions. Not a good thing.

I put in a call to Earl, but didn't get a callback. Anybody have any idea what
that part looks like?
