I had a little crash last time out, and half of my kill switch broke off in the process. It still works just fine and is easy to flick on/off, but I just want to double check that this will be all right with the tech inspection guys (for racing, not track attack):
That is a critical piece of equipment, we all sort of take it for granted. Like air, it's not important until you don't get any. For what it is worth and the consequence of it failing I would replace it.
