[quote author="mkruger"]It's easy to get lost on Digikey and other sites that have a million switches and lots of specs...[/quote]
Everyboy should get a Digikey catalog (and a Mouser catalog and an Allied catalog too). I've heard people complain that they order stuff and they never know if they're getting the right thing, or how what they get is never quite what they'd expected... With a catalog + the respective website, you can't go wrong. You get to see all the products in a given category right there in front of you, with part numbers, measurements, specs, prices, etc. Then you just type in the part number and hit the BUY button. Done.
And the catalogs are free.
Peace,
