I managed to remove the switches fairly easily with a heat gun, I had to make a little aluminum foil cone to focus the heat first. I attached a pair of mini vice grips to the switch itself, and then placed the PCB in a PCB holder. I flipped the board over so that the switch and vice grips were hanging down, applied the heat gun to the pins, and gravity did the rest! Getting the holes cleaned out and large enough for the pins of the new switch took a little more time, I used a soldering gun and a needle to widen them.
