Yes, you got it. I fixed it later on. Good eye.

Thanks. Because the high amps that the buck (dc to dc) converter could potentially draw. I do not like running high current through these types of switches, although they say they can handle 20A.. they tend to heat up. Thanks for watching

@@natesdiysolar ah ok. Good to know

@kaput808 but another reason is if you had the load far from the switch, you could use a smaller guage wire to operate the relay located near the load. Smaller guage wire = cheaper :)
