12V Battery Disconnect Switch - Manual Rotary Master Cut-Off for Car, Boat

How it works: Rotate the switch 90 upward to instantly cut battery power, and rotate it back down to restore power. Clear ON/OFF markings make operation obvious at a glance, so there's no electronics to learn and no room for error.

Stop battery drain before it starts: Batteries lose charge over time even when nothing's switched on - a slow drain that can leave you stranded after weeks in storage. This switch fully isolates the battery whenever your vehicle, boat, or equipment is parked or idle, helping preserve charge and extend battery life through winter storage, off-season downtime, or long trips away.

Built for a quick, clean install: The compact design fits standard battery terminals and common layouts, so you can install it in minutes using basic tools - no rewiring, splicing, or modifications required. A secure clamp connection keeps the fit tight and stable, even with regular use.

Goes anywhere 12V power does: Suited to cars, bakkies, RVs, boats, trailers, and other 12V systems - one switch, wide compatibility.

Safer. Smarter. More reliable. Protect what matters most.
