Perfect.
Easy install, works perfect and is a nice feeling knowing you’re not coming back to a dead battery due to a draw or something accidentally left on.I recommend.Thanks.

Really good solid switch
Nice quality switch, I've fitted it in my camper to direct the solar panel to either the leisure battery or to the van starter battery

If ever needed I’ll buy again
Absolute necessity if you have a boat. Especially if you have power trim so that you can completely cut all power to your motor in case a relay or contactor decides to stick. Have had for about 2 years on my boat and it sits in the weather every days and so far haven’t had a problem yet. Plastic has faded slightly but that’s to be expected when it’s in the sun daily. Also these are great because you can make sure there’s nothing on your boat slowly drawing power off the batteries.
