5.0 out of 5 stars Sturdy, does the job, and looks okay too
Reviewed in Canada on 27 October 2020
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.

5.0 out of 5 stars Battery disconnect switch
Reviewed in Canada on 7 January 2021
I used this switch to safely disconnect a bank of Lithium batteries from my 2000 watt inverter. This project was to provide backup power to my network devices in the event of a power outage or brownout. I was looking for a robust disconnect switch that could handle. There are other models of this switch. My requirements were quite simple and I had no need to switch between several batteries so this model works well for my needs and looks like it can handle the expected current loads easily. Again, time will tell...

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.
