 Thanks for the tip.  I have resorted to the same thing here - I plan on 
leaving the the switch on to see if that will help matters.  I think through 
some suggestions of others, I may have to investigate switching over the relays 
to small signal relays with gold contacts.  But If I get the urge to go play in 
the snow tomorrow where I can feel my fingers greater than 5 minutes, I may 
crack the switch open to see if there are any other issues going on.

This doesn't exactly answer your question but it was -30*C here this 
morning (it gets even colder sometimes) and it's (generally speaking) 
+/- 80% humidity here, pretty much year round.
Some years back I ran a RCSV-8 remote antenna switch and I am not 100% 
sure if it helped or not, but I always left 1 relay on always.  I 
realize the amount of &quot;heat&quot; produced by 1 relay would be very 
minimal,. but in my mind it may have helped. Did it?
 
Not sure, but since I started always leaving the 1 relay energized, I 
don't recall it ever sticking in the middle of winter.
 
These days I have other remote switches and 4-SQ controllers and none of 
them stick. (better quality than the old RCSV-8 though)
 
I have never tried it but I have heard stories about installing little 
light bulbs in an enclosure to not really keep it warm, but to drive out 
moisture.
