That was what my Dad mentioned too—he's built a lot of signaling systems for tower sites and radio studios and was nervous about me running 3.3v over any length

That was what my Dad mentioned too—he's built a lot of signaling systems for tower sites and radio studios and was nervous about me running 3.3v over any length of Ethernet. But he assumed we'd have shielded Cat5e at least... that would've helped somewhat.

That ensures that you have a sharp transition when the switch or whatever is closed or opened and that a floating voltage can't appear over time on your line and cause false triggers.
