They take some skill to solder and can melt easily so go in quick and use low melting point solder. By buying this switch you agree that you won't complain if you overheat and melt this switch.
If you do melt one, then it's possible in some cases to bring the switch back to life by pressing the actuator in and heat up the pins with an iron.
