As long as the vehicle does not move it won't activate! What's wrong with that?

If it is THAT sensitive, bumps from the push truck might trip it........

Always the one to try and be safe, I see in the 2009 rule book that inertial 
switches for fuel cut off are going to be required for 2010. So I purchased 
one from Pegasus racing thinking that they sell stuff used by the formula ford 
cars and SCCA cars as well. Well it came yesterday. Kinda spendy for such a 
small part. However, I am surprised at just how easy it is to trigger. If I 
have it in my hand and just briskly wave that hand around, it will trigger. AN 
dof course, it triggers when I hold it with one hand and bump with the other. 
I am really thinking that this particular unit may trigger in just a simple 
spin or near spin. Of course I guess I could mount it right on the CG and just 
a rotation of the unit woudl occur. The insructions for sure say not to mount 
it on a panel which can vibrate as that will trigger it. My questions are 
manifold. Are there going to be, if anyone knows, any kind of spec for these 
items? I would think that someting akin to an SFI spec is needed here. If a 
simple piece of foam requires it, then someting that might prevent a large 
fire should also need a spec as well. We have approved fire extinguishers why 
wouldn't this also need some kind of at least generic approval. Next question, 
for you folk that have these already installed. How much of a wiggle or impact 
did it or does it take to trigger yours? It may simply be that it is working 
fine and that I can move it fast and hard enough to trigger. I have sent the 
company an email asking what kind of g levels or just motion it would take to 
trigger it under normal or not normal circumstances. When I get the answer, 
I'll post it. Yes, I know that I could have gone to the junk yard and bought 
one. So exclude any comments about that please. As the same questions 
apply...what are the trigger levels.... comments? mayf
