Marine 2-Position Battery Switch - 277-000403

Average Customer Rating:  4.9 out of 5 stars   (13 Customer Reviews)


The new isolation switch has on the front face of the knob "Push to Turn" that alerts anyone how to turn it without damaging the switch.


Have not installed it as yet, ut appears to be the exact part we need. Appreciate the timely shipping. Have ordered from etrailer in the past. Always very helpful with any questions or problems. Highly recommend.

Product has consistently worked as it was described.
Theresa R - 09/06/2021


The battery switch worked great to disconnect my negative terminal on my 2021 Colorado. Chevrolet requires disconnecting in order to flat tow this vehicle.


Very good quality battery shutoff / disconnect. Mounts and wires up easily.


Easy installation, works as advertised. Don't have to keep disconnecting battery terminal when storing rv.


Good for new trailer


It works just like it is suppose to. What a relief that something works and I don't have to worry. It's great.


Works great, easy install


looks good. Thanks

  • Amp Ratings of Marine 2-Position Battery Switch
    I went to take a look for myself at the Marine 2-Position Battery Switch # 277-000403 and found it does indeed have a 300A continuous rating and 500A intermittent rating at up to 50V DC. I measured the screws with a digital caliper for you and they are 0.37 inches in diameter.

  • Switch Operation of Marine 2-Position Battery Switch # 277-000403
    The Marine 2-Position Battery Switch # 277-000403 only has two positions. On and Off. The knob should not need to be pushed down to turn either. It really shouldn't be coming off either. The actuator out position should be just a momentary switch function that activates but then goes back to off when you release.

  • Can a Battery Disconnect Switch Be Mounted Outside a Trailer
    The most weather resistant battery disconnect switch we offer is the Marine 2-Position Battery Switch part # 277-000403 which as the title states is a marine grade battery disconnect that holds an IP54 rating. That said, a battery disconnect switch is not designed to be mounted out in the open, subjected to water so you really need to find a way to mount the battery disconnect switch inside. The most common location is inside a battery box but I am not aware of one that will work on the...

  • How Does the Marine 2-Position Battery Switch # 277-000403 Install
    Basically you use install the Marine 2-Position Battery Switch # 277-000403 by cutting the wire for the circuit you want to install it on and wire one end of the wiring to either post underneath the switch. When the switch is "on" the circuit is completed and when it's "off" the circuit is deactivated. I attached a picture that shows the underneath side of the switch with the posts visible.

  • Installing the Marine 2-Position Battery Switch on Batteries Wired In Series
    Because your batteries are wired in series, you'll just wire the Marine 2-Position Battery Switch # 277-000403 between the batteries and your power distribution box. You can start by cutting the wire from the batteries to the main line of the power distribution box and then wire one end of the wiring to either post underneath the switch. When the switch is "on" the circuit is completed and when it's "off" the circuit is deactivated. I've linked a photo of the bottom of this switch so you...

  • Battery Disconnect Switch for Use on Travel Trailer
    You can use the Marine Battery Switch # 277-000403 for your application but since this item is not rated for outdoor use I recommend using a junction box like # 3375601100 to provide a degree of protection from moisture. The switch housing (not including the knob) is about 1-1/4-inches deep so you'd want to use hardware that is about 2-inches long. If space is available in your battery box you might be able to mount the switch there. In this case a better choice might be the Epicord Battery...
