[TowerTalk] up/down switch needed for US Tower HDX589

[Patrick Greenlee]

Sure, the existing switches ratings are above the minimum requirement but...

An argument in favor of higher than needed current switching capacity in 
this application is that with commonly available switches the heavier 
current switching switches are often more physically robust. There is no 
functional penalty for going for higher ratings than needed. A couple 
bucks "invested" in a more robust switch could very well be a wise 
investment.  But then I'm a belt and suspenders guy when it comes to 
specs and don't like to "cut it close."
