Topband: Freezing relays?

[R. David Eagle]

All,
I know everyone is experiencing the cold especially here in northern MI.  Last night I thought I would fire up the rig and do a few checks on my rx antennas and noticed none of them worked!  I was shocked as just a couple weeks ago they were all working.  I noticed one strange thing while switching the antenna switch around a few times that my selections were intermittent.  Some times they would work and sometimes they wouldn't.  Now, granted it was -10 here last night but, is it really possible that the relays have been so cold that the failed to fully actuate?  The relays in the switch are your standard automotive style rated about 10 amps.  I can't say for certain the quality of them though.  Is there a particular style/brand I should consider so I don't run in to this again?
Thanks again,
