Learning how to decipher the DigiKey catalog, for something like switches, is a valuable skill that will even serve you well in your job. Take the time, and don’t forget that for every manufacturer represented by DigiKey, there’s a manufacturer’s web site with detailed specs.
On the other hand, most of our switches also come from Radio Shack…
Given that you’re in Des Moines, WA, I highly suggest that you make the 20-minute trek over to Fry’s Electronics in Renton, WA. If the Fry’s in Southern California are any indication, they will have rows and rows of buttons, and many of them are in plastic bags so you can try them before buying.
Here’s a tip - buy some spares too. When we got to the regional last year, one of the switches had broken off in shipping. Since we had gotten it from Radio Shack, a replacement was just down the street, but we didn’t even need to do that. Another team had the identical switch and gave it to us!
We ordered 10 momentarys, a couple of rockers, and even some keyswitches off of DigiKey. For cool missle-style switches, Moddersmart.com offers them for $8.95 in a bunch of different colors, and free LEDs on the switch head
