How the points were given
Each switch is scored on performance, build, value, safety and warranty, with the weights published on the How We Pick page. None of the 5 states a UL, ETL or CSA listing, so all score zero on safety, and BURMONG and UCkasayfy state no warranty term.

Buying guide: best battery disconnect switch for rv
Current rating
Continuous current decides what the switch carries all day: FEITON lists 300A continuous, BURMONG lists 275A continuous, SUNMORN lists 150A continuous, and Jtron lists a 100A rated current with 200A max. UCkasayfy lists ratings by duration instead, 200A for an hour and 1250A for 10 seconds. Match the rating to the load the switch will carry.
Voltage range
FEITON, BURMONG, SUNMORN and UCkasayfy list 12-48V systems, while Jtron lists 12-24V only. A 48V bank needs a switch rated for 48V, so check the listing before wiring.
Waterproofing and build
SUNMORN lists IP66 waterproofing with a sealed O-ring, and UCkasayfy lists a fully enclosed design that protects wiring from dirt, corrosion and rain. FEITON lists an aluminum alloy heavy duty housing, while BURMONG, UCkasayfy and Jtron list ABS plastic housings.
Warranty
FEITON, SUNMORN and Jtron state a 1-year warranty. BURMONG and UCkasayfy state no warranty term, so the warranty is worth weighing against the rating.
Keys and indicators
Jtron includes 2 removable keys, and the key comes out when there is no power connection. FEITON includes an on/off indicator with a click, and SUNMORN includes a red/green indicator that draws no current once the switch is off.
Use rated jack stands on solid ground, wear eye protection with power and air tools, keep fuel-burning equipment out of a closed garage, and follow the manual for every tool. Read our Safety Disclaimer.
Garage Fit Check
- Check the continuous rating against the load: 300A on the FEITON switch, 100A rated on the Jtron switch.
- Check the voltage range: most switches here list 12-48V, while the Jtron switch lists 12-24V.
- For a switch that lives outside, check the waterproofing: SUNMORN lists IP66, and UCkasayfy lists a fully enclosed design.
- Keep the switch clear of plastic battery boxes and tighten both terminals before powering up, as the SUNMORN listing advises.
FAQ: garage tools
What is a battery disconnect switch?
A battery disconnect switch breaks the circuit between the battery and the electrical system, so the battery stops feeding clocks, alarms and stereos while the RV sits. The listings describe it as a cutoff that protects against drain, fire risk and theft when equipment is not in use.
How does a battery disconnect switch work?
Turn the knob or key and the switch opens the circuit, cutting power to the electrical system, and turn it back to restore power. The BURMONG listing states clear on/off positions on a 90 degree rotation, and the FEITON listing states an on/off indicator with a click.
How to wire a battery disconnect switch?
Follow the listing for the switch in hand: FEITON’s steps call for disconnecting the battery, choosing the negative cable, connecting the cables and checking operation, while SUNMORN mounts inline on the positive cable and calls for disconnecting the negative terminal first.
How to connect a battery disconnect switch?
Connect the switch inline on the battery cable with the battery disconnected, tighten both terminals before powering up, and check that the switch turns the power off and on, as the listings describe.
How to hook up battery disconnect switch?
Hook the switch up with the battery disconnected, mount it where the knob turns freely, and confirm the on and off positions before relying on it.
