Fun dc control panel.

Just ordered one of these for my van system.

Going to use the momentary start button and the relay to create a push for 24v to 12v converter circuit. The extra switches will be used to control individual low power 12V circuits (lights, fan, 12V outlet).

Reason to use a momentary start button is so the 24v to 12v converter can't be left turned on if the battery BMS ever does a low voltage disconnect. Plus I think it just looks cool.

Exactly. One of the joys of D.I.Y. is you can indulge your whimsy.

There, are you happy now whimsy?

Unfortunately whimsy is never satisfied. Its like you’re married to it or something.
