Default Re: Polycon from Fegusson failed

I've seen that sort of failure where someone has given a Polyvaricon 'a good squirt of switch-cleaner' then twiddled it.

The surface-tension of any liquid introduced between the plates and the interleaved dielectric-laminations can make them cling-together enough to tear the dielectric-sheets from their mountings.
