5.0 out of 5 stars Good, solid battery isolation switch.
Reviewed in Canada on 16 September 2021
I bought this to prevent small current drains from killing the battery on my 25ft travel trailer while it was in storage. Much easier than disconnecting a battery lead each time!
The switch is a good, heavy duty design. I wanted to mount it so that I could shut off the battery power from the outside of the battery box. I didn't know if the supplied mounting screws would be long enough. Happily they are. I have a group 27 battery box with a group 24 battery. There was easily enough room to fit the switch inside the box and still fit the battery. The switch fit perfectly through a 2" hole and the supplied screws were long enough to secure it. I used 4 stainless steel washers from the local hardware store to complete the installation. A bead of silicon secured the back cover of the switch to make a nice, waterproof installation.
One safety note. If using this on a trailer, it should be in the "off" position ONLY when the trailer is being stored! If you attempt to tow the trailer with it "off" position, two bad things can happen:
1. Your tow vehicle can't charge your trailer battery.
2. In the event of a trailer separation, the trailer brakes will not come on.

Arrived quickly. Installed on side of the single plastic Battery Box (using negative wire). Install was fairly easy, biggest time was lining up drilling the holes into the plastic box. I also removed the battery from the box so it would be easier to put in the screws and tighten the provided nuts properly. Easy to attach the negative wire . You will need to purchase another cable to run from the cutoff switch the the actual battery. Had no issues, worked first time. Great to have this for storage purposes and just in general so you can entirely shut off the electrical and avoid battery drain. Remember to turn on when hooked up and traveling, otherwise trailer lights, electric brakes, and charging the battery while driving will not take place.

3.0 out of 5 stars Function, but not easy to drill holes when installed in recessed way.
Reviewed in Canada on 31 August 2020
I purchased the simple on-off battery switch. Received today and installed immediately for disconnecting my trolling motor battery. Not used yet but it should function well.

I give it 3 stars because:

1. It is not easy to drill holes for the screws when installed in a recessed way. I tried to drill from the back with the switch as a guide with the switch in position (in the main hole). The regular 3/16 drill bit is barely long enough to make it through. I have to reposition the drill bit to make sure it at maximum length. It is not easy without a helping hand to hold it for me.

2. It does not make a “click” sound when you turn it on, it clicks reasonably when you turn it off.

The location I have it installed is not easy to watch from my seat when steering the boat. I hope it can give me a click sound for me to know it is on.

3. It feels slimy when tightening the nuts after connecting related cables to the battery and load. I installed a 4 position switch of a different brand on the same boat. In comparison, this one is not as strong. You need to tighten the nuts on the studs slowly with a ratchet.
