That was my take on it based on what some others said at the time.
A fuse is cheap, not so much the switch. Also, with no idea what load the wiring can take, an electrical meltdown or fire was not a particularly desirable outcome either. My thought was that in just using the switch as a relay "trip" I could size the wires, load, etc.beyond that point. I'm not an electrical guy, just my thoughts. It might all be okay, or not.
