silicone dielectric greases.

Tom,
I would tend to agree with you on this point, maybe it was the switch just 
breaking down ( Only digital signals no high voltages) and the small metal 
particles were causing further damage when loaded into the grease. Difficult 
to tell. I was surprised however and originally put it down to what I have 
just described. The Potable silicone grease was a local hardware company 
supplied item, cannot find the can just at the moment though so cannot put a 
name to it.
Worked very well for the original purpose which was to introduce into the 
SO-239/PL-259 connection on my Steppir antenna, never had any water ingress 
from there on.
