    • Works great worth every penny!
Color: On-Off Switch 275A
Put this in my boat as I think the clock on my stereo drains the battery between uses. Now I can just switch the dial to off and on when I run the boat. Now I keep a battery maintainer on it. Easy install you will need an allen wrench to hold the bolt while you tighten the 5/16 nut

    • Heavy Duty
Color: On-Off Switch 600A
This is a heavy duty battery isolator. The studs inside of it are 1/2 inch diameter which are too large for most battery terminals. The typical auto or truck battery terminal is 5/16 or 3/8 inch diameter so beware what your terminal has before buying this unit. It is bulky and may not fit in a tightly packed engine compartment. For my purposes it works great so I give it five stars. ... show more

    • Cheap to purchase but the In hand quality is far short of the Perko brand. Certainly functional.
Color: On-Off Switch 275A
I am not sure I would trust this running at near rated amps, I basically use them as a disconnect switch for mu Electronics and graphs on the boat. So far so good but time will tell if Perko was the better value. These turn on and off but feel mushy and lack the decisive click or thump the Perko switches have that feels like quality. Blue Sea is another top brand that likely has one of these compact marine switches. I am satisfied thus far for only a $14 purchase but with that said I am only running 4-6 amps through these or I would of Bought name brand. ... show more

Color: On-Off Switch 275A
Installed easily. But I recommend not using the bolts that come with it if you are going to mount this item. I found sheetrock screws worked a lot better.

    • Best Purchase
Color: On-Off Switch 50A
I mounted this on a switch panel so I can have a master on/off switch for my battery and it's perfect. If you have a four panel (or however many) switch with the 12 volt (cigarette lighter), just unscrew that and put this in that spot and you are golden. Super easy!
