I think your conclusion is correct. Has to be. The way I think,
though, is that the more switches/relays you have, the more you increase
the chance of one failing. I have relays to control my fuel pump and my
electric fan and those haven't failed yet. But I've had some relays
(the cube-shaped ones) fall apart in my hand, so I don't 100% trust
their integrity. I ty-wrap them to the socket to prevent them
physically falling apart, and carry spares.
I once had a kill switch fail. It wouldn't close, and I missed a race.
I carry a spare one of those now, too.
