Question 1

Will this switch drain my battery when not in use? I’ve seen conflicting info about the display draw.**

Accepted Answer

Great question—and a common one! The switch itself draws just 0.001A in standby (that’s 1 milliamp), which is effectively nothing. The LED voltage display does draw about 0.01A while actively lit, but only when the switch is ON. Once you flip it OFF, the display turns off completely. Many TikTok users tested this with multimeters and confirmed it won’t drain a healthy battery over months of storage. For absolute peace of mind, you can always disconnect the switch entirely during long off-seasons.

Question 2

I’m installing this on a boat/RV that sits outside—is it weatherproof?**

Accepted Answer

The switch body is water-resistant but not fully submersible. We recommend mounting it in a dry compartment or adding a simple rubber boot if it’s exposed to rain or splashing. Reddit users in fishing forums noted it works fine on covered boats, but direct spray can cause condensation inside the display. If your setup is fully exposed, consider pairing it with a waterproof housing—many owners do this and report zero issues.

Question 3

The included terminal bolts seem short—will they fit my thick battery cables?**

Accepted Answer

You’re not alone in noticing that! The bolts work well for standard 6–8 AWG cables, but if you’re running thicker 4 AWG or 2/0 lugs, you may need to buy longer 10mm bolts (M8 thread). Several YouTube installers recommend using stainless steel bolts from a hardware store for corrosion resistance. The switch itself accepts up to 2/0 cable, so the bottleneck is just the bolts—easily swapped.

Question 4

Can this switch be accidentally turned off while driving?**

Accepted Answer

It’s designed to stay put. The knob requires a firm quarter-turn, and it has a positive detent—meaning it clicks into place. We’ve seen no reports of it vibrating loose on Jeeps, tractors, or trucks. That said, if you’re mounting it in a high-traffic area (like near your knee), a protective cover or recessed mount can prevent any accidental bumps. For 99% of installations, it’s rock-solid.

Question 5

I’m new to electrical work—is this hard to install?**

Accepted Answer

Not at all! It’s basically a heavy-duty on/off switch. You disconnect your battery, attach one cable to each terminal (polarity doesn’t matter), mount it with the included bracket, and you’re done. The voltage display works automatically when the switch is on. Dozens of first-time installers on Reddit called it “easier than changing a headlight.” Just make sure your wrench is the right size (10mm or 13mm)—and watch a 2-minute tutorial if you want to see it done step by step.
