Solder lug is the term you're looking for.

I mean, you can still solder that to a board if you don't mind a chintzy butt joint (i.e., the lugs just butt up against the PCB, and a generous solder fillet is all that's holding it down). If you have enough space to form the terminals, you can get more of a gull wing or flat lead joint, still SMT.
Better is using slot shape thru pads, and soldering the terminals into the board that way. You probably can't use round holes (like you can with round or square pins), because they'd have to be way too large. (Most fabs don't complain if you use slotted pads, it's pretty standard.)
Best? Idunno, giving up and panel mounting it (and using wrapped and soldered wires, heat shrink -- a whole harness assembly) is way too much effort, plus it takes up space that you might not have, to begin with. Maybe "better" should be changed to "best" above?
And yeah, good switches are stupid expensive, at least in small quantities. Hard to find in good styles too. It bothers all of us.

You could always risk it on some Ali Express junk, maybe it'll turn out alright -- if not, you're only out a couple of bucks, equivalent to as much time you've already spent writing and reading in this thread already! (Never lose your perspective on this sort of thing. Unless you're doing it a thousand times over, it simply doesn't add up, to keep searching for something truly competitive!)
