Richard, FYI...I appreciate your efforts to discredit the existence of these switches. Often, posters are second or third owners of these coaches and unfortunately the manuals that come with them are seldom passed along. Helping the folks on here to better understand how their machines work is the goal of the forum. At any rate, below I've attached a couple photos from my manuals depicting the switch with photos and a brief description of what it does. While Monaco refers to them as a battery cut-off switch, (as opposed to a battery DISCONNECT switch), they are more commonly referred to as "salesman" switches because they cut off 12V power to the domestic fuse panel only and not all power as a battery disconnect switch would....Dennis
