I am just about to wire up an expansion to the layout.  I had planned to use these mini terminal bars to quickly hook up both the drop feeders/bus wires AND the switch leads.[img]http://i168.photobucket.com/albums/u172/dcrane_2007/terminalbar.gif[/img].  I checked to see that the small gauge switch leads will be held tightly by the terminal blocks...and all is fine in that regard.But I got to thinking...these contacts are very open to the air and perhaps to tarnishing and corrosion from ordinary household humidity.  The layout is in a pretty well controlled environment, but perhaps even so over time the contacts within these blocks might fail.Has anyone an opinion or experience hooking up the wiring this way?  I have seen these used well for the bus wire set up, but worry more about the tiny wires for the switches.  I am just using Atlas HO code 83 snap switches....have had no problem with them in the past in any regard.
