Winch Interrupt Switch

To read the original full thread and post questions/comments on this topic, please go to

Decided to use a battery cut-off switch to take out power to my winch. Didn't want any tree-huggers to go to town on my FJ's roof. The switch itself is a Hella Battery Master Disconnect, rated for continuous 150 amp, and a surge amp rating of 1,000 amps. The wiring itself is real simple, just run the cable connect from the winch to one post, and another cable from your battery to the other post (see pic #3).

Here's the information for one similar to the one I used.

Titan Winch brought up a valid safety concern about the switch possibly failing under the varying draw currents from winch to winch. So, take this under consideration when/if applying a battery disconnect. I plan on taking a look at some of Hella's higher rated switches to see if can be made applicable for my use.

Was concerned about the switch just dangling out in the open in the engine compartment, so I decided to enclose it. Modified/cut a Radio Shack project box to fit.

Drilled a couple holes on each side of the enclosure, allowing the cables leading to the winch and another cable to the battery access to the switch.

All closed up and mounted. I thought about applying silicon and making the enclosure completely water tight, but decided it really wasn't necessary. Instead, I drilled a couple drainage holes at the bottom facing side of the box.

No juice.

EDIT: Here are some more switch options.
