I recently changed from a motorhome to a small travel trailer.I have the typical 12 volt battery mounted on the tongue in the plastic box.When in storage I like to unhook the battery.Rather than unstrapping the box,removing the cover and unbolting a cable has anybody found a switch that can be mounted in the side of the box?

I have one like this that I put in my RV and it does very well for complete isolation. I think it was around $30.
Blue Sea Systems marine. This model has connections for two batteries.

I mounted a Blue Sea m-Series Switch on the side of my battery box years ago, still works just as it should. [emoticon]

Since this pic was taken I've replaced the flooded battery with an AGM and moved the box to the front pass through storage compartment but still use the switch. Highly reliable. [emoticon]

While I agree with Juzaxadar, he linked a 2 circuit switch (that I made a clicky).
You only need a single circuit switch: https://www.amazon.com/Blue-Sea-Systems-Selector-Battery/dp/B000MMC914?th=1

What you're needing is a "Master battery switch". There are less expensive ones than Blue Seas for a single circuit disconnect. Some even have a removable key, should you need more security:
Keyed master switch

I went thru two of those cheap switches in one season, they corrode inside and cease to make contact. My Blue Sea has been working ever since.

Agree - I've got at least 4 of those keyed switches sitting in a junk drawer in my workshop and every one of them has failed, the Blue Sea m-Series switch I bought years ago and I've not had any issues with it at all.

The BLUE SEA switches contact areas are sealed and make before break to reduce arcing. I have been using everything BLUE SEA since 2008 and switches are still performing as they did when i got them...

The other thing I like about the BLUE SEA Products switches and bus bars etc is I get to use 5/16-inch ring terminals everywhere... Makes for neat connections.

I was introduced with the BLUE SEA products in my working years with the SPAWAR Navy bunch from Charleson SC building up things for their shore station electronics systems etc...

I recently bought a 1 year old used travel trailer that had a switch on the battery. While I was talking to the owner, I asked if he always had it turned on while towing and he said that he turned it on when he got to his destination. I asked him if he realized that he was not charging his battery while driving and that his breakaway switch had no power to activate if needed? He didn't realize that he was driving without the breakaway being useless. I talked to several people while I was on vacation and some of them were driving without the breakaway being powered also. Please check your systems.
