Does anyone know of a kill switch that is "hot" (flowing current) when you are clipped in, and that breaks the circuit when you clip out?

The one I have now (Gunnar) is "off" when clipped in, and then completes the circuit when unclipped. The Emgo is the same, and I believe the Pro-Design is also. I have one end spliced into the orange positive wire at the coil and the other end grounded.

My problem is, my CDI box keeps blowing. I have the Dyna FS. I ran it this way with the stocker for a year with no problems, but ever since I went to the Dyna, it seems that everytime I pop the kill switch it messes up the Dyna box. I would like to find a "reverse" kill switch so that I can wire it into the stock thumb engine stop switch and eliminate any doubt that I have that the kill switch is whats destoying my $400 CDI box. Thanks for any info you can give,

My banshee is running the dyna with the pro-design switch going from the orange wire to ground. I have had no problems. My first dyna had to be sent back though and they sent me a new one.
