Near Intersection of I-35 & I-90 Southern Mn. | I have installed the one above on my Eagle truck right in the battery box. I drilled a hole in the aluminum box with a hole saw and two other holes to mount the switch mostly to the outside with some spacers and long bolts. This works well on my truck since the battery box is on the left side. When I shut off the switch, I remove it so it is dangling by the chain to alert me next time before I crawl in. Deere uses this same switch on my 8310R tractor.
My switch breaks the ground connection. To do this the negative or ground posts were already connected together and I rerouted the last one to my switch. The other post of the switch connects to the truck frame. The truck had an electric tarp and third axle added which had gone directly to the batteries. I rerouted those grounds to the frame. With the switch off all ground connections are broken. I have had no battery draw down problems since installing and using this switch. The only downside is my AM/FM radio loses its presets and correct time.
