Does anyone know if this battery switch will work?

[062720]

I have a question... I picked up a switch that is suitable for wet locations like this at my local HD: http://www.homedepot.com/buy/electri...tch-86936.html

I also picked up an industrial 30 amp switch like this: http://www.homedepot.com/h_d1/N-5yc1...&storeId=10051

can this application be used as a battery switch since its rated 30 amps rather than a typical bulky battery switch like the one used here by harvey at post#52 here: http://www.trailmanorowners.com/foru...0812#post90812

if so the only question that I have is how do I connect a typical battery wire to the switch?

Unless I missed something that is not a switch, but a switch cover. You will need a switch and a waterproof box. When you are done it will be fairly large. I suggest something like this (link below). It is water proof and small enough to mount in your battery box. To wire up, make up a short piece of #10 stranded wire with terminal lugs on each end. Connect one end to the positive terminal of the battery and the other end to one terminal of the switch terminals. Connect the terminal that used to go to the positive battery terminal to the other switch terminal. You are done. Switch avail at most any marine store.

Your second Home Depot link doesn't work for me, but I bet you are looking at item number R52-03032-2WS which is a 30-amp double pole switch. My answer is YES, this should work with the switch cover referenced earlier. As Bob/Rumbleweed mentioned, you will need a weatherproof box to mount the switch and the cover. And just to add some spare switch capacity, I would wire the two halves of the switch in parallel, so that each carries part of the load. But I see nothing wrong with it.

Thanks bob and bill... you both confirm what I thought... that is that it can be done... I'm a bit unsure what bill ment by connecting to the other side of the switch... i have a double pole so I have (2) screws on one side and (2) on the other on the switch... then I have a green ground on the side that is separate.

as per my second question above: how do I connect this: http://www.jdxpwj.cn/products.asp?id=1296 to this: http://www.google.com/products/catal...d=0CFcQ8wIwBA#

The problem is that the battery cables loop is too big to fit into the switch screws you see. also as you probably know the screws don't come all the way out of the switch.

From your questions are you sure you have the skills to safely do this?
Do you understand the difference between series and parallel circuits?

These are not meant to be negative, they are posed to insure a safely installed project.

The switch you have chosen will work but isn't the best for the application.

You will need spade crimp connectors for the switch, they look like this

They need to be for the wire size you are using and stud size you are using.


With the switch in your hand as shown in your picture a jumper between the top two screws will do what Bill talked about. A second jumper between the bottom two screws will complete what he talked about.

This places the switch contacts in parallel and reduces contact resistance.

The wire and fuse disconnected from the battery goes to one of the bottom screws.

Your new wire goes to one of the top screws, have the switch off before connecting this wire to the battery.

Please ask more questions if any of this is unclear before starting.

I used a water resistant switch from West Marine.

I have one similar to:

LOL, yeah i've been known to get myself in trouble sometimes... I understand electrical enough but I am not fully confident. Your explination made me confident. I know what a parallel vs series connection is but never made one on a switch befor so this is the reason I was double checking myself.

I get myself into those situations sometimes also. Just keep asking questions and someone on the forums will have an answer is what I've found.
