It's not possible to add the pins onto the switch really unless you've got a lot of time and super glue... they're attached to the plastic piece on the bottom of the housing.
Hopefully this can help you get a better understanding:
From Left to Right, Plate mount, PCB mount, PCB mount with snapped off pins

Ah, I see. Some arts and crafts pro may be able to get it down! Lol jk
And Which way is more recommended to switch out the switch? By soldering it or popping the cap off? Or are they the same?(just want to get an idea of what the majority of you do)
edit: Thanks for the pics btw much appreciated!
