Air step mercury switches

[jim riordan]

Don,

I quite can't picture what you are talking about. Are you talking about the
mini cherry switch?
If so I beleive that it is a flat sheet of metal held by two nuts on the
piston rod on either side, which makes contact with the cherry switch.

with drawings. Didn't sound too hopeful.
