Nitrous plumbing A1A...??..

If it were me, I would not install that bypass switch. If I ever accidentally left it in bypass mode, the low pressure protection switch would be useless.
I personally would have a jumper wire or the bypass switch with alligator clips so that it’s a tool used only when necessary. Then it stays in my tool box until actually needed.
You know that was my very first thought was to put some kind of jumper wire between them when I needed it and then I thought it would be more convenient to have a switch. Maybe a compromise between the two is having a fusible link and just sticking the fuse in there when I need it and pulling it out under normal circumstances?..
