This thing is tough!
This switch turns on and off with a pleasant, distinct "snick." I am running a 200amp alternator with two Optima batteries on my race car. It was easy to modify the switch handle of this product to accept a hinged extension rod connected to a remote kill-handle by the taillight outside of the car. This puts mod puts extra tension on the switch body, but this thing is so solid that it doesn't seen to care.

Works great
I like these battery disconnect switches and they work great and easily. The only drawback is the need to drill a hole to mount the main shaft through, which is just over a 1/2" in diameter. When drilling through the steel panels of construction equipment, this can be a real chore. Assembly and wiring is straight forward. There is a definite 'positive' click when you flip the switch, giving a solid confidence the switch is where you want it, either in the 'On' or 'OFF' position.

Holds up to the weather.
Pretty stout, I've installed about 4 or 5 of them and they've seem to be holding up.
