KILL SWITCH/electric guitar recommendations?

[Rick Walker <looppool@cruzio.com>]

I had a URL for a  KILL SWITCH for a custom tenor guitar
I"m having made, but it no longer is extant.

These came highly recommended and I wondered if anyone has any 
experience with them.

But I've also heard that video game switches can be faster to manipulate 
than
typical guitar styled 'kill switches'.

The standard toggle switch on a guitar is not really fast enough for very
quick 'slicing and dicing' techniques,  so I wondered,  what's the poop
on KILL SWITCHES?

Anyone know what Torn uses,   out of curiosity?

Thanks,
