If you use the Massoth insulated rail-clamps, they come with 'solder tags'. - ring terminals you solder a wire to.
These can be done away from the track, so easier to work with.
Alternatively, you can get crimp-on ring terminals, but there is a knack to fitting / using these, as well.,
Whatever switches you get, the more protection you can give them, the better..
You can get 'chunky' switches, where the connectors are either push-on blades (we call them 'Lu-Car') or even a screw you can fit a ring terminal to..
It all depends on what you can get locally, and how much you are prepared to spend.
