I have no doubt that safety cutout switches are a leading cause of failure, but if harmonic vibrations are enough to make it toggle, you probably don't have a strong enough spring on the switch lever. Replace that stupid switch on the side stand with a chunk of rubber on the end of the side stand foot and you have a simple device that does the job of an overly complex one.
Tip over-switch :/ is a mercury switch, it's not going to make contact unless you tip it upside down, gravity and liquid mercury is very predictable.
