Recs for Solar Cut Off Switch?
Looking for help finding some sort of cut off switch that I can mount on the wall inside my coach next to where the charge controller is currently mounted. Side note: I'm pretty much hemmed into p...

Hi,
On AC power the direction of the voltage changes 30 times a second. On DC it is one way, so an arc requires a larger gap.
Here is a high voltage example:

That is what is happening inside the switch. The arcing causes pitting of the contacts.

With respect, using a switch rated for AC in a DC circuit may lead to arcing.
Don, what are the design characteristics of AC and DC switches that differentiates the two? What inhibits the arching in one design and not the other. Inquiring minds want to know.
