Re: [PSUBS-MAILIST] Waterproof controls

[Warren Greenway <opensourcesub@yahoo.com>]

I work with LCDs all the time, and most LCDs,
especially
ones that aren't backlit are very resistant to
pressure.
It will generally cause temporary problems, while
under
pressure, but then clear up when the pressure is
reduced. Most of those severe duty boards can actually
be run wet, with the exception of the power contacts.
