To remove the switch caps you pull up on them on the opposite side as
they are hinged. So where they normall push down, you pull up. But the
little pins that hold the cap on can get bent easily.
Removing the entire switch is difficult due to the thick mounting leads
that get soldered to the board. It's very difficult to remove all the
solder from these leads in order to just pull the switch out, and it is
also difficult to heat them all up at the same time if you try that
technique. Often, we just destroy the switch by cutting away the plastic
body of the switch so we are left with only the pins soldered to the
board, and then each pin can be removed one at a time.
The risk you run trying to remove the entire switch intact is that you
could easily pull up when the switch is not completely desoldered, and
then you're going to end up pull the traces up off the board, which
could ruin the board.
