Yes seperating the switch is a delicate affair. I was very careful to
ease the two tabs. Even a small amount of heat can help. Finger nails are best as you can feel the tension. Since repairing mine I've had no further issues.
I can't think of any precaution other than possibly glueing the green nub into the spring.
If you want to fly me out I my rates are cheap - beer mainly, but none of the nats piss.
