Electrical circuits where batteries are involved require extra care. If such electrical circuits are not taken care of properly, then those may cause short circuits and fire. Also, when the circuit is in idle condition, the battery may drain and get damaged. So, a battery switch is an essential component to use in an electrical circuit. When you add a battery switch to an electrical circuit, then that can disconnect the battery from the circuit to keep it safe.

One of my best purchases for our travel trailer. So glad I bought this. It really cuts down on the battery drain while the RV is in storage. There are usually electrical drains on the battery and this prevents/reduces that along with accidentally leaving lights etc on. I think I drilled 4 holes into the battery box, bought one length of additional battery cable (from Amazon) and basically interrupted the negative cable with this switch then added the new cable to complete the route back to the neg terminal. If you own a travel trailer, you need a battery disconnect switch!

This works very well. It has a solid construction and positive action when turning the switch. The internal cable lugs have good quality hardware including lock washers. The provided SS mounting hardware is of very high quality, and comes with locking style nuts, but is a bit small (in diameter). It is sized well for what it needs to do, but the small size makes it a bit difficult to work with.

Toggle switches are great for just about any electrical project. One of the things that I wanted to do for my Snapper mower, bypasses the zone start safety mechanism. Every time I have to leave the mower to pickup a piece of trash, a child’s toy, or even empty the grass bag, the mower dies. So I bypassed the original setup, and I installed one of these switches on the operator’s console.

Had some equipment where the switch went out, the old ones were of lower rating so these worked just fine, I like the fact that it came with rubber covers to protect the switch after screwing it on so that liquid and dust doesn’t get into the switch itself.

Worked perfectly! Kills power to the camper so it doesn’t drain my battery when parked. Hooked my solar charger directly to my battery so it is sure to stay charged.

I am using this to control navigational lights and the bilge pump on a Boston Whaler. I didn’t want the led to be on all the time, so did some exploring. Attached is what I believe to be the internal wiring. Disconnecting the red wire from lug #4 deprives the “off” led of power and hence it does not light and drains the battery. Note the female spades come off easily if you squeeze the built-in clip with needle-nose pliers.

I used it to control the tank heaters on my RV. It looks great and the 20 Amp switches can easily handle the load. I really like that the small lamp indicates the master power is on and the large lamp indicates that the heater is on.

This switch keeps my Motorhome chassis/engine battery from draining during storage times. Apparently, there is quite a drain on motorhome batteries even when the engine is off, and the battery goes dead in just a few days. A fully discharged battery will eventually die completely if not recharged. This switch has saved my battery; saved me from jumping it; and giving me peace of mind.

This two-pack of Ampper battery disconnect switches was a very good deal here on Amazon. I only needed one to use on my truck to keep the battery from running down while parked during periods of extended non-use. The disconnect appears to be made out of cast zinc or something similar with a brass color coating and a solid brass disconnect screw with a green plastic knob and white plastic insulator between the two halves, which is adequate enough for what I’m using it for. It was easy to install and is doing what I need it to so I’m happy with the purchase.

Buying Guide For Best Battery Switches

A Battery switch is a simple item to buy for your car or any other electrical system. But, you can’t go to the market and pick any battery switch and use that. So, here are some important factors to consider while buying a battery switch for your application. 

1. Consider The Power Requirements 

You can check the voltage and current rating of your electrical system to choose the compatible switch for that. Once you have calculated the voltage and current requirements for your circuit, you can look for the switches that meet that specification. While choosing the battery switch, you must pick a higher specification switch than your electrical circuit for optimal performance. If the switch has lower voltage and current ratings than the circuit, then the switch may get damaged while using. 

2. Check The Movement Style

Usually, you can find the battery switches in toggle, push-button, and rotary style. All three styles are ideal for offering high performance. However, you must check the voltage and current rating of the style of the switch you are going to buy. If you only consider the style and don’t consider the power ratings, then you may get the wrong battery switch for your application. 

3. Installation Type 

Installation type is another important point to consider in a battery disconnect switch. Some battery switches come with screws for installation, while some other battery switches include a simple locking feature to get attached to your equipment. So, while buying a battery switch, you should consider the installation process to install that effortlessly. 

4. Warranty 

Generally, a battery switch handles heavy currents and voltages to keep your circuit safe. So, the switch may get damaged if that doesn’t have robust construction. If the brand offers a long warranty period, then you can get assured that the battery switch can be used for a long time. Also, you can claim the warranty if the switch gets damaged. So, you can look for the battery switches with at least a 2-year warranty period for a better experience.   

Conclusion 

By using a battery switch, you can ensure the safe performance of your vehicle. If you are unsure about the type of battery switch required for your vehicle, you can use the buying guide and product reviews to choose the best one.
