Can i use these with DC voltages?

These switches are rated at 5/120 and 3/240 AC , contacts are silver plated which is good for AC but not for DC since platting is so thin and contact resistance so good you will end up with weld contacts, I have been using these switches on 30 ma up to 500ma no problem what so ever

I'm not an electronics person, so I'm not sure how to read the diagram; what are each of the terminals for? How do you wire this switch into a circuit

It depends on the circuit which you will be wiring the switch into. A wire needs to be connected to the (C)ommon connection opposite of the roller. You then need to determine if you need the switch in the open or closed position when the switch is not activated. I use the common and the normally open for my CNC milling machine limit switches.

Any recomendation of spade Wire Connector for it? 3.3mm is odd size.

the connections are solder lugs, not too well suited for use with a female spade connector. The switch dimensions dictate the size of the connections, and limit them so that, when installed, the connections won't contact a mounting surface. Plus -- the nature of use, with something actuating the switch mechanically, somewhat dictates a more mechanically secure connection than you might expect with a push-on connector. If you must use one, consider a short flexible wire pigtail soldered to each terminal, then add the connector of choice to the end of that wire for your chosen connector.

Good switches for the price

So far so good! These come in a pack of 10 which makes this a pretty good value. I cannot attest to durability since they have not been in use for long enough, but they do seem solid. Response on these seems proper. I am using them in a slightly non-conventional way (as a button of sorts) but they are doing the job nicely.
